America's Time Zones

When you are very much used to something, it's hard to perceive how weird it is to outsiders. Most nations of the world are small enough to exist in only one time zone. And then there's China, which is very big and still only has one time zone, but that's a different story. Anyway, I live pretty close to a time zone border, and have always been conscious of how to calculate the time elsewhere. When living in Central Time, I got used to everything on TV being an hour earlier than it should. The lines between zones aren't straight, and the reasons why are inexplicable. But someone who has never had to deal with time zones may find them confusing. Laurence Brown of Lost in the Pond explains how he first encountered American time zones and what it took to get used to them. There's a 77-second skippable ad at 3:20.
