Personally, it would be brilliant if we'd just go to permanent daylight savings time nationwide. The transition is hard on the kids and living in the northern part of the country, the extra daylight is appreciated.
I think we should shift time zones a little every day, so that (in some designated location, say New York or DC) the sun rises at exactly 6am every morning.

By the way, what you describe is how things worked prior to standardization of time which was driven in part by the expansion of the railroad. There's a brief history on Wikipedia:
