Imo the obsession with "solar/astronomic" time is weird. I kinda get the reason - a) we humans hate any change, b) we humans reaaaally like pretty and symmetric concepts. By why exactly it is "a must" that high point of the sun matched with 12:00 precisely? Who cares about that for a valid reason instead of tradition and fear? Why not match it with 11:00 or 13:00 or literally any time point?

Countries have long singe transitioned from the rural lifestyle and should adjust life and healthcare conditions for a majority, not for minority. A majority of population should get as much daylight as possible, for the best long-term health outcomes.

It should be a pretty simple and easy task for professional statisticians. Compile average outside time for every age and every job cohort, overlay them and we will get a nice graph with two nice normal deviation peaks - morning and evening. Then shift a daylight graph (which would be a single very wide "peak" of sorts) overlaid over that outside time graph by adjusting timezone point/center. Play with it until the area matching on both graphs is maximized and bingo - that's the optimal timezone for a majority of population.

I suspect with AI help it can be done in a week by a tiny team, instead of years and decades of baseless shouting and finger pointing and name calling in press, parliament and random social networks.
