This is definitely not an issue I think that can be solved by merely doing away with time zones. Time zones at least in the US were part of coordinating arrival and departure times for the railroad which was a big problem when two towns that were mere miles apart were on two different times (sometimes by an hour). I think the real problem is that every governing body involved with time measures seems to think theirs is the best. UTC is awesome but by itself it's not enough to synchronize with local habits which are dictated by solar time (even when considering the most extreme ranges of time zones). At the heart of the matter is how do you fix time zones such that governments respect solar time over their own desired time frame fork human activity? Honestly, I have no solution beyond a fierce beating of the average legislator/bureaucrat. Because honestly timezones should be in 15 degree slices around the Earth since that approximates well with the shape of it. Mind you, for people living near or at the poles is going to be a mess for them regardless of how you settle it but the majority of humans a simple 15 degree slice of the Earth gets the time zone problem as close to a solution as possible. But the odds of any major government (or even local government) adopting this is nil. So I just pray no one actually tries to reform the existing timezones otherwise we'd might get something worse.
