That's what time zones are. You're just proposing more granular time zones. And none of them can fix the problem that in a lot of places the days are just short in the winter.
Timezones don't account for seasonal changes in sunrise times, and DST is a poor hack that tries and fails. Using local solar time would be an improvement in that regard. On short days you just do less.
Timezones are a reasonable compromise between the desire for people to be up during the day, on one hand, and the need for a modern economy to be able to coordinate people over long distances, on the other. Turning up the dial all the way to the left here is going to cause a lot of problems.
