Question

Who cam4e up with the distances between timezones throughout the world today?

Answer 1

If you mean the angles between them, they're just a 24th of the world each (with wiggles along national borders to keep the same time zone for smaller countries spanning two time zones).

The Greenwich meridian was chosen as the datum as when they were standardising this, Greenwich was a very important maritime dock (Brittania still ruled the waves) and this was mainly useful for maritime navigation.
