The only appropriate physical criterion to verify which correct timezone to be in, is the one that has the Sun (mean Sun at least, let's temporarily ignore the Equation of Time) within 7.5 degrees of true South, at midday.

This gives an equal amount of daylight before and after the center of the day.

For a country's timezone, pick the geometric centre of population, and pick that location as the place to determine the timezone from.

Anyone that complains about school times, business start times, you do of course realise that these can be arbitrarily changed if so desired. It's much easier to change a school class start time than the rotation of the earth after all. It's also much easier to change an average office day start time than to change every clock in the country.
Howdy kayak.

Thanks for a well thought out reply.

I can see office hours to not be as rigid when professional life gets back from home-office, if it ever fully will, really.

Changing school times..I don't think it will happen in the next 2 decades. But there's been a lot of research done in productivity and cognition linked to schedules.
