Why can't you eat when you're hungry?

Why can't you go to sleep when it gets dark?

A better way to manage when things should happen is to create a schedule which could be defined in UTC. I don't think the time zones really solve this problem.

For example, I might assume that I can eat dinner when my plane lands in my destination around 8pm. But when I look for a local restaurant, they all close at 8pm because it's a smaller town. I still need to look at the hours of operation for that business.

So I can't really make assumptions based on the local time anyway so why do we need to adjust them.

Excellent question! We would probably need to remove the concept of "days" because that is relative to the current planet.
