Chic... It would be really tough... It would be like not having rotating months depending on what hemisphere we live in.

Can you imagine what life would be like if it wasn't cold in February no matter what part of the world one was in?

I think all you would need to know was what time was "high noon" in a particular city of the world, and that's about it.

How much of anybody's day would be effected if a guy in Hungary said that noon was at 7PM?

As a matter of interest. China uses ONE time zone even though it spans FOUR...

They just have different start/stop times for work.
