The Problem of Time Around the World

The problem of time around the world is really interesting if you think about it. Not only do the Southern Hemisphere have winter when we in the North but they're having our summer. It's also true that what looks like 10 o'clock to us, let's say in Boston, doesn't look like 10 O'clock in Los Angeles. So the problem of time goes beyond daylight saving and goes all the way back to trying to understand how we can get us all together on a single clock.
