The number of timezones is pretty irrelevant. It's that there is a 3 hour time difference between the East Coast and the West Coast. (And an 8-9 hour time difference between the West Coast and Europe.) But the only real way to deal with that is to shift Pacific Time to Mountain Time.

I can't see how my message wasn't clear enough. This is exactly what I meant. Did you think I was suggesting to remove a timezone without adjusting the remaining ones to reduce the time difference between the coasts?
