And I love the idea of eliminating timezones, especially the example that pilots already use UTC. Ever considered this might be because the concept of "day" doesn't really apply when you change 10 timezones in 10 hours?
Personally I think eliminating timezones would make relating to people internationally very difficult. It's already weird enough that Australians think of December as a summer month. Consider half the world thinking of 20:00 (8PM) as the morning. How does "everywhere is the same hour" even remotely fix the fact people sleep at night and work at day anyway?
And what do you do with an extra week "every five or six years"?
