As the world gets more "global" I think time zones are kinda becoming obsolete and a universal time keeping system could make more sense than the wall clock reflecting when true solar noon is.
I like that. With UTC, the actual time would be absolute, with no qualifiers. Doesn't seem like it would be any more trouble for each "zone" to adopt a system of adjustment for working hours, per daylight schedule than it is now to account for who is in which time zone.
