My idea? Just make sunrise in each time zone the new 6:00 am every day. That's right; reset all clocks every single day. Now, we'd still have time zones so it'd be a little arbitrary, but, whatever. At least it'd make sense biologically. There's be lots of retail and manufacturing activity as people rushed to create and sell "one-push-reset" clocks and whatever paraphernalia would link us all to some service or other, for those who can't or won't see the sunrise themselves.
My other idea is to have "Fall Back" every week. So you'd reset your clock back one hour every Saturday night. Yeah, we'd be awake in the dark sometimes and sleeping in the day some times, but whatever. At least it would follow our circadian clocks (generally speaking.)
