It’s 2 a.m. and we’re snoozing into Sunday’s Central Standard Time (CST) in Manitoba

Provincial governments come and go in Manitoba, like elsewhere, but one of things that doesn’t change is my email reminder around this time every year: “Manitoba Municipal and Northern Relations reminds all Manitobans that daylight time will end in Manitoba early Sunday morning when clocks will be set back one hour,” the new NDP government’s Manitoba Municipal and Northern Relations department, presided over by Minister Ian Bushie, cheerily told me yesterday.

“Under the Official Time Act, daylight time ends on the first Sunday in November and resumes the second Sunday in March.

“The official time change back to central standard time will occur this year at 2 a.m., Sunday, Nov. 5 at which time clocks should be set back to 1 a.m.”

So at 2 a.m. in the morrow, we’re snoozing into Sunday’s Central Standard Time, (CST) in Manitoba, with our gratitude renewed for Scottish-born Canadian surveyor, engineer and inventor Sir Sandford Fleming, who we thank profusely for the extra hour of sleep.

While it has been gradually getting darker earlier in the evening since late June here in the Northern Hemisphere, the fact many of us, at least until tomorrow, can still travel home in waning daylight from work or school in the late afternoon in early November is in itself a credit to George Vernon Hudson, an English-born New Zealand amateur entomologist and astronomer who gave the world Daylight Saving Time (DST), a decade or so after Fleming’s development of Standard Time.

Hudson’s day (and sometimes night) job was as a clerk (eventually chief clerk) in the post office in the capital of Wellington on North Island. Hudson’s shift-work job gave him enough leisure time to collect insects, and led him to value after-work hours of daylight for that pursuit when he was working days. On Oct.15, 1895, spring in New Zealand, he presented a paper called “On Seasonal Time-adjustment in Countries South of Lat. 30°”  to the Wellington Philosophical Society, proposing a two-hour daylight-saving shift, and after considerable interest was expressed in Christchurch on South Island, where 1,000 copies of his paper were printed in 1896, he followed up on Oct. 8, 1898 with a second paper, “On Seasonal Time,” also presented to the  Wellington Philosophical Society in springtime, and which can be found in the Transactions and Proceedings of the Royal Society of New Zealand, housed at the National Library of New Zealand in Wellington.

It is Fleming, however, who deserves most of the credit for both the international dateline, and standard time zones, conveniently divided into hourly segments, dating back to October 1884 and the International Prime Meridian Conference attended by 25 nations in Washington, D.C. Before Fleming invented standard time, noon in Kingston, Ontario was 12 minutes later than noon in Montréal and 13 minutes before noon in Toronto. Noon local time was the time when the sun stood exactly overhead. As for the international date line, it is an imaginary line at the 180º line of longitude that runs from the South Pole to the North Pole separating two consecutive calendar days.

It was Hipparchus of Nicea, a Greek mathematician and astronomer, who around 150 BCE, proposed a global grid of longitude and latitude lines to measure position. It was a coordinate system for locating points on the surface of a sphere. The vertical axis measured “latitude,” and the horizontal axis “longitude.”

Immediately to the left of the international date line the date in the Eastern Hemisphere is always one day ahead of the date (or day) immediately to the right of the international date line in the Western Hemisphere. There is no regulatory body or agency that can say “yes” or “no” if a country wants to switch sides. The country simply lets the international community and mapmakers know. It is not a perfectly straight line, however, and has been moved slightly over the years to accommodate needs of varied countries in the Pacific Ocean. The Midway Islands are in Coordinated Universal Time (UTC) -11, and the Marshall Islands are in UTC+12. The two group of islands, on different sides of the international date line, share the same day and date for the last hour of the day. Samoa, which happens to sit in the middle of the Pacific Ocean, just 32 kilometres, or 20 miles, east of the international date line, went directly from Thursday – on Dec. 29, 2011 – to Saturday, Dec. 31 – without a Friday, Dec. 30. Talk about being anxious to party on New Year’s Eve!

Kiribati, north of Samoa and near the equator, south of Hawaii, previously straddled the dateline. The eastern part of Kiribati was a whole day and two hours behind the western part of the country where its capital is located and a time difference of 23 hours between neighbouring islands. There were nine islands on the eastern side of the international date line, and 20 per cent of the population. On Jan. 1, 1995 it added an eastward extension to its section of the dateline so all 33 of its islands would have the same date and all of Kiribati would be in the Eastern Hemisphere.

Since 1892, when Samoa had two Monday, July 4ths, it had been east of the international date line until Dec. 29, 2011, after switching sides to coincide its days better with trading partners in the United States and Europe. Now, Samoa does a lot more business with New Zealand, Australia, China and Pacific Rim countries such as Singapore, so it switched back to the western side of the international date line.

After missing a train in 1876 in Ireland because its printed schedule listed p.m. instead of a.m., Fleming proposed a single 24-hour clock for the entire world with 24 time zones and within each zone the clocks would indicate the same time, with a one-hour difference between adjoining zones. Usually, when one travels in an easterly direction, a different time zone is crossed every 15 degrees of longitude, which is equal to one hour in time. Usually. China, however, has just one time zone, which makes the time zone uncommonly wide. In the extreme western part of China the sun is at its highest point at 3 p.m. and in the extreme eastern part at 11 a.m. In 1912, the year after the collapse of the Qing Dynasty, the Republic of China had created five time zones in the country, ranging from five and a half to eight and a half hours past Greenwich Mean Time. But in 1949, as the Communist Party consolidated control of the country, Chairman Mao Zedong ordered that all of China use Beijing time.

Fleming was born on Jan. 7, 1827 in the town of Kirkcaldy in the lieutenancy area of Fife on the east coast of Scotland. He emigrated to Canada in 1845, settling in Peterborough in southeastern Ontario.

This year, as we shift back to Standard Time from Daylight Saving Time at 2 a.m. tomorrow, which means an extra hour of slumber for many, but also causes me to ponder the potential complications of moving the clock back an hour and repeating the hour from 1 a.m. to 2 a.m. What happens when the clock jumps backward at 2 a.m. again to 1 a.m. for the second time that night and then repeats the hour? Would you have official log chronologies showing 1:13 a.m., 1:37 a.m., 1:56 a.m., 1:03 a.m. and 1:12 a.m. with the later two actually coming after the first three because they came after the clock fell back an hour? How would you distinguish which came first if need be, if someone needed to inspect the log months later (add the annotation 1:13 a.m. CDT or 1:03 a.m. CST?)

Most of Canada’s time experts work in a place called Building M-36 (which involuntarily conjures up for me visions of the X-Files and Area 51.) They work in the Frequency and Time program in the Measurement Science and Standards portfolio with the National Research Council of Canada (NRC) on Montreal Road in Ottawa. Physicist Rob Douglas, the principal research officer, however, can be found on Saskatchewan Drive in Edmonton.

Douglas explained to me years ago that “in a handwritten log the hour of ambiguity to which you refer can be simply resolved by appending the time zone (e.g. CST or CDT) to potentially ambiguous entries … e.g. “01:32 CDT” for the first pass through the hour of ambiguity and “1:32 CST” during the second pass.

“By explicitly writing the time zone as part of the time entry,” Douglas added, “you also bypass the time acts’ defaults for official time – as you might wish to do if you are making agreements across a time zone boundary where there is the possibility of geographic ambiguity of time zone.

“The above procedure is very clear in Canada, but unfortunately less so in the USA,” said Douglas. “We in Canada can refer to ‘official’ or ‘legal’ time, which can alternate between being a ‘Standard Time’ or being a ‘Daylight Time.’ In the USA, to allow regulation by the federal government, both ‘Standard Time’ and ‘Daylight Time’ must be considered a ‘standard’ to avoid having time changes be a state responsibility under the residual powers clause of their constitution. If you think you may have to deal with the American ambiguity, it may be worthwhile to include an explanatory note in the log, such as ‘CST is defined as UTC-6h, and CDT is defined as UTC-5h.’

“If the times are being logged in a permanent logbook, with entries in chronological order for a fixed reckoning of time (i.e. in the absence of clock adjustments), then a simple way of removing the ambiguity is to include in the appropriate place in the log an entry such as “02:00 CDT – log’s clock changed from CDT to CST – 01:00 CST.

“If the log is a computer log, by using the operating system’s timestamps (for example as the time recorded for a file’s modification) the problem disappears since these timestamps are recorded as Coordinated Universal Time (UTC – the modern version of Greenwich Mean Time) which is never subjected to Standard/Daylight changes. The operating system re-interprets these timestamps into its version of the correct local time in effect for the particular UTC timestamp, and this re-interpretation may unfortunately still be expressed ambiguously, but the underlying UTC timestamp can be used to resolve any ambiguity about time zones and Daylight/Standard time.”

Sci-Fi time travel: Where the popular imagination meets theoretical science and pseudoscience

Applied research often has the clarifying effect of disabusing one of preconceived notions. Except perhaps for debates about religion where all bets are off for everyone on all sides at all times. But that’s another story.

Every now and then I will post an article or a link to one on social media from some at least marginally reputable science site on some new wrinkle in theoretical time travel. I have three friends, in particular, located in British Columbia, Nunavut and Manitoba, who are sci-fi fans, but also science rationalists, who can be quickly counted on to let me know two things: what a fun idea the new theory is; how completely implausible it is on the science. Thanks, guys.

As a kid, while I enjoyed reading some science fiction – Ursula K. Le Guin‘s Lathe of Heaven from 1971, and Arthur C. Clarke’s 1953 book Childhood’s End, come immediately to mind – I was also fond of other genres, including Greek mythology (I remember taking a mighty tome home on the subject from my school library and reading it from start to finish one Sunday in Oshawa, where I learned a bit about the Hippoi Athanatoi). Time travel was just one topic within one genre of my reading interests back then.

But aside from my reading interests, in terms of my later popular culture viewing, on both the big and small screens, as well as my own writing from time-to-time, time has never been too far from my remote view, if I think broadly about it.

Both The Time Tunnel on ABC and Star Trek on NBC television series originally debuted within a day of each other in September 1966. I was nine. The Time Tunnel (https://www.tvyesteryear.com/shows/the-time-tunnel/), largely forgotten today, was about Project Tic-Toc, a top-secret U.S. government effort to build an experimental time machine, known as “The Time Tunnel” due to its appearance as a cylindrical hallway. The base for Project Tic-Toc is a huge, hidden underground complex in Arizona, 800 floors deep and employing more than 12,000 specialized personnel. Star Trek made its debut on Sept. 8, 1966, one day earlier then The Time Tunnel, and is far from forgotten.

Manu Saadia, a contributor for The New Yorker, wrote back in 2016 in “The Enduring Lessons of ‘Star Trek,”‘ a 50th anniversary piece to mark the debut of the franchise, that “the original series was at its best when its cast engaged in good, old-fashioned time travel. ‘The City on the Edge of Forever,’ penned by Harlan Ellison, threw the dynamic trio of Kirk, Bones, and Spock into nineteen-thirties New York. They were familiar characters dropped into a familiar setting, tasked with a familiar, if daunting, mission: save the world. (By a series of unlucky coincidences, their arrival in New York had altered the future, leading to Nazi Germany winning the Second World War. This had to be corrected.)” Joseph Walter of Screen Rant in his piece today, “Star Trek: The 10 All Time Best (And 10 Worst) Episodes, Officially Ranked” rates “The City on the Edge of Forever” as the sixth-best Star Trek episode from the entire franchise, which includes all the series that followed the original, which aired on NBC from September 1966 to June 1969.

Star Trek, and its many successors, both television series and movies, not surprisingly have continued to explore the idea of time travel and alternate timelines in all kinds of manifestations. I like many of them, but have a particular fondness for Dr. Beverly Picard, who in a briefly existing alternate timeline in “All Good Things,” the aptly-named May 23, 1994 final episode of Star Trek: The Next Generation, is the captain of the U.S.S. Pasteur (NCC-58925), as her ex-husband, Capt. Jean-Luc Picard, inexplicably finds his mind jumping between the present stardate 47988 and the past just prior to the U.S.S. Enterprise-D‘s first mission seven years earlier at Farpoint Station and then flash-forward 25 years into the future, where he has retired to the Picard family vineyard in Labarre, France.

In The Man in the High Castle, an alternate history novel by American writer Philip K. Dick, published and set in 1962, events takes place 15 years after a different end to the Second World War, and depict intrigues between the victorious Axis Powers – primarily, Imperial Japan and Nazi Germany – as they rule over the former United States, as well as daily life under totalitarian rule. A television series was loosely adapted from the book and ran for four seasons from January 2015 until last November.

In a similar vein, The Plot Against America is a novel by Philip Roth published in 2004. It is an alternate history in which Franklin D. Roosevelt is defeated in the presidential election of 1940 by Charles Lindbergh. Adapted for television as a six-part miniseries that aired in March and April, The Plot Against America imagined an alternate American history told through the eyes of a working-class Jewish family in Newark, New Jersey, as they watch the political rise of Lindbergh, an aviator-hero and xenophobic populist.

Wormholes and parallel universes are pretty much de rigueur for this genre, and Sliders, a television series which aired between 1995 and 2000, understood that, as it was premised on a group of travelers, led by Quinn Mallory, using a wormhole to “slide” between different parallel universes. Alternate timelines are altered versions of our timeline. Unlike parallel universes, alternate timelines do not seem to diverge from the universe, but instead rewrite history to the point of wiping out the original timeline.

For its first two seasons, Sliders was produced in Vancouver. It was filmed primarily in Los Angeles in the last three seasons.

In Quantum Leap, which aired on NBC for five seasons from March 1989 through May 1993, Scott Bakula stars as Dr. Sam Beckett, a physicist who leaps through spacetime during an experiment in time travel, by temporarily taking the place of other people to correct historical mistakes. Dean Stockwell co-stars as Admiral Al Calavicci, Sam’s womanizing, cigar-smoking companion and best friend, who appears to him as a hologram.

Time Changer is an independent science fiction Christian seriocomic film written and directed by Rich Christiano, and released by Five & Two Pictures in 2002. The screenplay concerns Dr. Norris Anderson (Gavin MacLeod), who uses his late father’s time machine to send his colleague, Bible professor Russell Carlisle (D. David Morin), from 1890 into the early 21st century.

The fascination with alternate timelines is not limited to science fiction writers. Historians have been known to wonder if the 1963 assassination of President John F. Kennedy, in ending Camelot, changed the course of history for the worse? It’s a popular, if not almost universal view, that it did. But historian David Hackett Fischer, in his 1970 book, Historians’ Fallacies: Toward a Logic of Historical Thought, warns of the dangers of counterfactual historiography, which extrapolates a timeline in which a key historical event did not happen or had an outcome which was different from that which did in fact occur. Had Kennedy lived would the United States have exited Vietnam closer to 1964 than 1975? Would Lyndon Johnson’s landmark Civil Rights Act of 1964 have passed so soon under JFK? We can only wonder.

In 1983, Ohio State University historian Stephen Kern wrote The Culture of Time and Space, 1880-1918, a book which talked about the sweeping changes in technology and culture that reshaped life, including the theory of relativity and introduction of Sir Sandford Fleming’s worldwide Standard Time – and an onrush of technics, including telephone, electric lighting, steamships, skyscrapers, bicycles, cinema, airplanes, X-rays, machine guns, as well as cultural innovations that shattered older forms of art and thought, such as the stream-of-consciousness novel, psychoanalysis, Cubism, simultaneous poetry. All of these things created new ways of understanding and experiencing time and space during that almost 40-year period ending with the end of the First World War. Kern’s argument is that in the modern preoccupation with speed, especially with the fast and impersonal telegraph, international diplomacy broke down in July 1914, leading to the outbreak of the First World War the following month.

In physics, according to Albert Einstein’s 1905 theory of special relativity (SR), motion in space alters the flow of time, creating a time dilation, speeding up or slowing down time, because as you move through space, time itself is measured differently for the moving object than the unmoving object. This, in theory, would allow time travel within the known laws of physics into the future, not into the past (https://soundingsjohnbarker.wordpress.com/2016/03/12/time-dilation-daylight-saving-time-and-other-mysteries-of-time/).

Standard Time, of course, with its standardized times zones, is a Canadian invention, courtesy of Sir Sandford Fleming, who conveniently divided time into hourly segments, dating back to October 1884 and the International Prime Meridian Conference attended by 25 nations in Washington, D.C. Before Fleming invented standard time, noon in Kingston, Ontario was 12 minutes later than noon in Montréal and 13 minutes before noon in Toronto. Noon local time was the time when the sun stood exactly overhead.

Most of Canada’s time experts work in a place called Building M-36 (which involuntarily conjures up for me visions of the X-Files and Area 51.) They work in the Frequency and Time program in the Measurement Science and Standards portfolio with the National Research Council of Canada on Montreal Road in Ottawa. Physicist Rob Douglas, the principal research officer, however, can be found on Saskatchewan Drive in Edmonton.

Fleming’s genius was to create 24 time zones and within each zone the clocks would indicate the same time, with a one-hour difference between adjoining zones. Usually, when one travels in an easterly direction, a different time zone is crossed every 15 degrees of longitude, which is equal to one hour in time (https://soundingsjohnbarker.wordpress.com/2015/03/07/just-remember-you-are-about-to-pass-briefly-through-the-twilight-zone-nothing-can-happen-tomorrow-between-201-a-m-and-259-a-m-because-those-59-minutes-do-not-exist-on-march-8/). Like many things, there are, of course, exceptions. Samoa uses Coordinated Universal Time (UTC+13:00) as standard time and UTC+14:00 as daylight saving time, which it observes during summer in the southern hemisphere. The U.S. territory of American Samoa, as well as the Midway Islands and the uninhabited islands of Jarvis, Palmyra, and Kingman Reef, use the Samoa Time Zone, which observes standard time by subtracting eleven hours from Coordinated Universal Time (UTC-11). The zone is one hour behind the Hawaii-Aleutian Time Zone, one hour ahead of Howland and Baker islands, and 23 hours behind Wake Island Time Zone.

Samoa happens to sit in the middle of the Pacific Ocean, just 32 kilometres, or 20 miles, east of the International Date Line, an imaginary line at the 180º line of longitude that runs from the South Pole to the North Pole separating two consecutive calendar days. Immediately to the left of the International Date Line the date in the Eastern Hemisphere is always one day ahead of the date (or day) immediately to the right of the International Date Line in the Western Hemisphere (https://soundingsjohnbarker.wordpress.com/2014/09/29/skip-a-day-why-not-samoa-did/).

It is not a perfectly straight line, however, and has been moved slightly over the years to accommodate needs of varied countries in the Pacific Ocean. Kiribati, north of Samoa and near the equator, south of Hawaii, previously straddled the dateline. The eastern part of Kiribati was a whole day and two hours behind the western part of the country where its capital is located and a time difference of 23 hours between neighbouring islands. There were nine islands on the eastern side of the international date line, and 20 per cent of the population. On Jan. 1, 1995 it added an eastward extension to its section of the dateline so all 33 of its islands would have the same date and all of Kiribati would be in the Eastern Hemisphere.

Since 1892, when Samoa had two Monday, July 4ths, it had been east of the International Date Line until Dec. 29, 2011, after switching sides to coincide its days better with trading partners in the United States and Europe. Now, Samoa does a lot more business with New Zealand, Australia, China and Pacific Rim countries such as Singapore, so it switched back to the western side of the International Date Line.

China, which has just one time zone – Beijing Standard Time – making the time zone uncommonly wide. In Kashgar, in the extreme western part of China, the sun is at its highest point at 3 p.m. and in the extreme eastern part at 11 a.m.  In 1912, the year after the collapse of the Qing Dynasty, the Republic of China had created five time zones in the country, ranging from five and a half to eight and a half hours past Greenwich Mean Time. But in 1949, as the Communist Party consolidated control of the country, Chairman Mao Zedong ordered that all of China use Beijing time.

Historians aren’t the only academics to ponder these sort of things.

Massachusetts Institute of Technology (MIT)  professor of philosophy Bradford Skow suggests a “box” universe theory, as describes “now” as an arbitrary place in time and states that the past, the future and the present all exist simultaneously, suggesting that if we “look down” on the universe, as if we were looking at a piece of paper, we would see time spanning all directions, exactly the same way that we see space at some point. I believe my three friends unanimously concluded this was rather bunk, but good fun.

Standardizing time: Canada’s Sir Sandford Fleming

Thank Scottish-born Canadian surveyor, engineer and inventor Sir Sandford Fleming if you’re getting an extra hour of snooze time Sunday morning.

“Under the Official Time Act,” the Province of Manitoba helpfully reminded me in an e-mail Thursday, Oct. 29, 2015 at 2:06 p.m. (CDT), “daylight saving time ends on the first Sunday in November and resumes the second Sunday in March.The official time change back to standard time will occur this year at 2 a.m., Sunday, Nov. 1 at which time clocks should be set back to 1 a.m.”

While it has been gradually getting darker earlier in the evening since late June here in the Northern Hemisphere, the fact many of us can still travel home in waning daylight from work or school in the late afternoon in late October is in itself a credit to George Vernon Hudson, an English-born New Zealand amateur entomologist and astronomer who gave the world Daylight Saving Time (DST), a decade or so after Fleming’s development of Standard Time. Hudson’s day (and sometimes night) job was as a clerk (eventually chief clerk) in the post office in the capital of Wellington on North Island. Hudson’s shift-work job gave him enough leisure time to collect insects, and led him to value after-work hours of daylight for that pursuit when he was working days. On Oct.15, 1895, spring in New Zealand, he presented a paper called “On Seasonal Time-adjustment in Countries South of Lat. 30°”  to the Wellington Philosophical Society, proposing a two-hour daylight-saving shift, and after considerable interest was expressed in Christchurch on South Island, where 1,000 copies of his paper were printed in 1896, he followed up on Oct. 8, 1898 with a second paper, “On Seasonal Time,” also presented to the  Wellington Philosophical Society in springtime, and which can be found in the Transactions and Proceedings of the Royal Society of New Zealand, housed at the National Library of New Zealand in Wellington.

This year, as we shift back to Standard Time from Daylight Saving Time at 2 a.m. tomorrow, which means an extra hour of slumber for many, but also causes me to ponder the potential complications of moving the clock back an hour and repeating the hour from 1 a.m. to 2 a.m. What happens when the clock jumps backward at 2 a.m. again to 1 a.m. for the second time that night and then repeats the hour? Would you have official log chronologies showing 1:13 a.m., 1:37 a.m., 1:56 a.m., 1:03 a.m. and 1:12 a.m. with the later two actually coming after the first three because they came after the clock fell back an hour? How would you distinguish which came first if need be, if someone needed to inspect the log months later (add the annotation 1:13 a.m. CDT or 1:03 a.m. CST?)

If you think you may have to deal with the American ambiguity, it may be worthwhile to include an explanatory note in the log, such as ‘CST is defined as UTC-6h, and CDT is defined as UTC-5h.’

“If the times are being logged in a permanent logbook, with entries in chronological order for a fixed reckoning of time (i.e. in the absence of clock adjustments), then a simple way of removing the ambiguity is to include in the appropriate place in the log an entry such as “02:00 CDT – log’s clock changed from CDT to CST – 01:00 CST.

The operating system re-interprets these timestamps into its version of the correct local time in effect for the particular UTC timestamp, and this re-interpretation may unfortunately still be expressed ambiguously, but the underlying UTC timestamp can be used to resolve any ambiguity about time zones and Daylight/Standard time.”

It is summer back home right now in São Paulo, Brazil. It is hot. It was still 30°C in São Paulo at 10 p.m. Brasilia Summer Time (BRST) tonight. But Ben Weber and Natalia Almeida don’t have to worry too much about that. Not at all in fact. Because for the last several years, come summer in Brazil, they’ve been in the northern hemisphere, here in Canada, or the United Kingdom three years ago, as part of their 360 Extremes Expedition they launched on Dec. 1, 2011 where they are traveling round-the-world in a series of annual treks, exploring big chunks of geography, not from east-to-west, which is the norm, but instead along the north-south polar axis.

While Antarctica and the South Pole closer to home are their ultimate adventure goals, which Weber and Almeida are spending years training for, this year they’ve just begun their Cetaphil Arctic-Canada Challenge, which began Dec. 20, 2014  at the Canada-United States international border crossing at Emerson, Manitoba, and will end 2,175 miles north at Resolute Bay on Cornwallis Island in Nunavut, the second northernmost community settlement in Canada, next to Grise Fiord on Ellesmere Island. Only Eureka, which is a weather and scientific outpost, and Alert, a Canadian Forces military station, are farther north still than Resolute and Grise Fiord. Weber and Almeida hope over the course of their expedition to eventually be the first to complete the polar axis circle traveling largely by land, cycling through the heat of the Gobi and Australian deserts,  climbing the high altitudes of the Himalayas and Mount Everest, completely traversing the North Pole and South Pole in one expedition.

Before leaving South America, Weber and Almeida trained late last year for their Cetaphil Arctic-Canada Challenge by completing a cycling trip from São Paulo to Santiago, Chile, via Buenos Aires in Argentina. Weber picked up their windsuits and bicycles for their Cetaphil Arctic-Canada Challenge in England in late November.

On Jan. 7, Weber and Almeida rode their  26-inch wheel size Oxford Bike Works chrome-molybdenum steel alloy frame bicycles, built by British bicycle builder Richard Delacour, whose one-man shop in Oxfordshire in the Midlands is famous for neither over-engineering or over-pricing its touring bikes, up Highway 6 and into Thompson to hang out for a few days and regroup, staying with Tim and Jean Cameron on Campbell Drive, as they get ready to make the switch at Gillam, which has a population of 1,281 and is 302 kilometres northeast of Thompson by road, from  winter cycling to skiing the rest to the way to Resolute Bay. They rode in on regular non-studded tires, although they do have Schwalbe Marathon winter studded 26-inch tires with them if needed. Tires are always something of a trade-off. The thicker they are, the more puncture proof and longer-lasting they are usually are, but thicker tires also adds to rotational weight and increases friction, which slows you down.

Tim is the province’s chief natural resource officer, with Manitoba Conservation and Water Stewardship, while  Jean is the Canadian Imperial Bank of Commerce (CIBC) branch manager here. As the hosts of the Home Routes Borealis Trail house concerts here for the last three years –  and for three years before that in Ashern – the Camerons are used to having some of the more interesting house guests passing through Thompson, as they provide hospitality, including food and lodging for the musical performers in town for a show.

Weber blogged they arrived in Thompson Jan. 7 “after a hard couple of weeks and some of toughest cycling we’ve done! Now we will change over to skis: a little bit of a transition period as we have to sort them out together with our pulks and supplies, so there will be a week or so of relative inactivity, but then we will hop over to Gillam to ski north for over 2,000 kilometres to the Arctic Circle and the town of Resolute. We will cycle the part from Thompson to Gillam after we manage to finish that part: the sea ice up north won’t wait for us and starts breaking up in June, so we have to start making headway on it as soon as possible. The road to Gillam will be waiting for us for when we get back!!”

Weber grew up in the Orkney Islands in northern Scotland, and is a fellow of the Royal Geographical Society and a member of the Brazilian Adventure Society. When he’s not training, he works as a consultant, supporting companies coming to Brazil, helping them deal with a complex business and political environment.

In an interview at the Thompson Regional Community Centre (TRCC) Jan. 9, Weber said he quit his full time job almost a year ago and now freelances, so he can train better. He said he had worked in Brazil for about 10 years before Almeida and he began their 360 Extremes Expedition in December 2011.

More than three years later, Weber said, he’s a few pounds lighter than when they began, but what’s changed more is his ratio of body fat to muscle mass, with not surprisingly more of the latter now.

Does he miss São Paulo, a global metropolis of almost 12 million residents, making it Brazil’s most populous city, and the world’s 12th largest city by population, even in the heat of their summer? Weber smiles and says sometimes when’s he’s eating from the camp rations in the tent at night after a day’s winter bicycling through Northern Manitoba, he wistfully recalls briefly some of his favourite São Paulo’s restaurants.

Almeida is a veteran television editor, who has led the editing teams of many mainstream TV programs in Brazil, such as those covering the Brazilian car rally, the Rally dos Sertões – going through the dry back country of the Brazilian northeast, and Policia 24h – a program accompanying police in São Paulo and Rio de Janeiro on the job.

While it is their first time in Thompson, Weber and Almeida are no strangers to the Canadian North and Arctic. Last March and April they undertook polar survival training near Iqaluit with NorthWinds Arctic Adventures Limited’s Matty McNair, and Sarah McNair, the youngest person to reach both the North and South poles, before Weber and  Almeida embarked on their Auyuittuq Expedition through Auyuittuq National Park, starting out in Qikiqtarjuaq, well north of the Arctic Circle,  and working their way south to Pangnirtung.

In 2012, they traded some of their Brazilian summer for a United Kingdom winter, spending 20 or so days cycling the famed Land’s End to John O’ Groats bike route, where riders traverse the entire 1,500-kilometre length of Great Britain, from  Land’s End, the extreme southwestward  point of Great Britain, situated in western Cornwall at the end of the Penwith Peninsula, and John O’ Groats, the traditionally acknowledged extreme northern point of mainland Scotland, in northeastern Caithness.

Skip a day? Why not, Samoa did

Admit it. Is there anyone out there who hasn’t wanted to “skip” a day now and then? After all it is Monday morning where I am writing right now.

If you lived in Samoa in the Pacific Ocean you got a chance to do just that – although you had to wait until the end of a Thursday  – on Dec. 29, 2011 –  when Samoa jumped straight from Thursday to Saturday, Dec. 31 – without a Friday, Dec. 30. Talk about being anxious to party New Year’s Eve!

Well, truth be told, that’s not quite the official explanation. You see, Samoa happens to sit in the middle of the Pacific Ocean, just 32 kilometres, or 20 miles, east of the International Date Line, an imaginary line at the 180º line of longitude that runs from the South Pole to the North Pole separating two consecutive calendar days. Immediately to the left of the international date line the date in the Eastern Hemisphere is always one day ahead of the date (or day) immediately to the right of the International Date Line in the Western Hemisphere.

It is not a perfectly straight line, however, and has been moved slightly over the years to accommodate needs of varied countries in the Pacific Ocean. Kiribati, north of Samoa and near the equator, south of Hawaii, previously straddled the dateline. The eastern part of Kiribati was a whole day and two hours behind the western part of the country where its capital is located and a time difference of 23 hours between neighbouring islands. There were nine islands on the eastern side of the International Date Line, and 20 per cent of the population. On Jan. 1, 1995 it added an eastward extension to its section of the dateline so all 33 of its islands would have the same date and all of Kiribati would be in the Eastern Hemisphere.

Since 1892, when Samoa had two Monday, July 4ths, it had been east of the International Date Line until Dec. 29, 2011, after switching sides to coincide its days better with trading partners in the United States and Europe. Now, Samoa does a lot more business with New Zealand, Australia, China and Pacific Rim countries such as Singapore, so it switched back to the western side of the International Date Line.

There is no regulatory body or agency that can say “yes” or “no” if a country wants to switch sides. The country simply lets the international community and mapmakers know. Samoa announced its most recent intentions last April.

The dateline, and standard time zones, courtesy of Canada’s Sir Sanford Fleming, conveniently divided into hourly segments, date back to October 1884 and the International Prime Meridian Conference attended by 25 nations in Washington, D.C. Before Fleming invented standard time, noon in Kingston was 12 minutes later than noon in Montréal and 13 minutes before noon in Toronto. Noon local time was the time when the sun stood exactly overhead.

Fleming’s genius was to create 24 time zones and within each zone the clocks would indicate the same time, with a one-hour difference between adjoining zones. Usually, when one travels in an easterly direction, a different time zone is crossed every 15 degrees of longitude, which is equal to one hour in time. Samoa uses Coordinated Universal Time (UTC+13:00) as standard time and UTC+14:00 as daylight saving time, which it observes during summer in the southern hemisphere. The U.S. territory of American Samoa, as well as the Midway Islands and the uninhabited islands of Jarvis, Palmyra, and Kingman Reef, use the Samoa Time Zone, which observes standard time by subtracting eleven hours from Coordinated Universal Time (UTC-11). The zone is one hour behind the Hawaii-Aleutian Time Zone, one hour ahead of Howland and Baker islands, and 23 hours behind Wake Island Time Zone.

Pretty clear, eh?

But then there is China, which has just one time zone  –  Beijing Standard Time  –  making the time zone uncommonly wide. In  Kashgar, in the extreme western part of China, the sun is at its highest point at 3 p.m. and in the extreme eastern part at 11 a.m.  In 1912, the year after the collapse of the Qing Dynasty, the Republic of China had created five time zones in the country, ranging from five and a half to eight and a half hours past Greenwich Mean Time. But in 1949, as the Communist Party consolidated control of the country, Chairman Mao Zedong ordered that all of China use Beijing time.
