Also, no mention of the need for only 10 big-ass time zones instead of 24 relatively narrow time zones. The continental US might have only 2 time zones instead of 4.
This is already the case, timezones have weird shapes and some of them are huge.
In Europe and China you have timezones spanning over 3 "sun" timezones. In practice that means the sun rising and setting at different times. People are used to have the sun setting late or rising early depending where they live.
Wouldn't this actually be confusing, because things would have to be happening at different local times depending on where you are in the time zone?
