True, but time zones offer a good compromise between solar time and globally-synchronized time.

Having 12pm noon be approximately when the sun is highest in the sky is better than not at all, and still gives some form of regional cohesion in terms of timekeeping.

There are pretty extreme examples, of course; China is one entire UTC+8 time zone, and that means Tibet is still dark when Shanghai is wide awake, which is dumb, and as annoying as the US’s 4 time zones is (not counting Alaska and Hawaii), it still makes regional sense.

Fuck daylight savings time.
