Why time zones in Canada and the US got so weird

Transcript

Look at the time zones of Canada and the US. Everything looks pretty normal. Regions located mostly along the same longitude use the same time. And it's a pretty common thing to cross into a different time zone when traveling east or west. But on November 1st, at 2am, everything changed and things got really weird. Just look at Calgary in Alberta and Destin in Florida. They're separated by more than 2,000 miles and nearly 30 degrees of longitude. But now their time is the same. And over here, it's the opposite. Vancouver and Seattle are almost on the same line of longitude, just one degree apart. But the time difference is a whole hour. So the train from Vancouver to Seattle takes 3 hours according to the schedule. While the return trip takes a full 5, even though each trip actually takes about 4 hours. And there are now dozens of situations like these. But how did this happen? You see British Columbia, Alberta, Manitoba, and the Northwest Territories decided not to switch to wintertime this year. Just as Saskatchewan and Yukon have done for many years. So in most other regions turned their clocks back an hour, that caused a shift. But in the spring, when the clocks move forward again, everything should return to normal.
