The Earth says. It takes 24 hours to revolve. > Why aren't they separated by 30minutes, or 20, or 10? Or 2 hours? Why isn't an hour defined to be 30 minutes? > Or why don't we have a global time?

The 25 timezones I speak of are not merely an abstraction, but related to longitude. > as are the 400 apparently in use by people all over the world Where the correlation to longitude is much looser. Granted, it doesn't need to be for non-navigational purposes.

Isn't there some law somewhere that says the circumference of a sphere is 360deg? Doesn't that same law mean that no two points on a sphere can be seperated by more than 180deg longitude? Doesn't that make GMT+13 non-sensible? > > Diez -- http://mail.python.org/mailman/listinfo/python-list
