Exactly. By GP's logic, time zones are absolutist, and every town could & should observe solar noon independently.

I think folks are averse to "world time" (for reasons, largely inertial), so maybe the baby step is try 1 timezone per country (like China's done for .. 75 years ?).

I'd even argue Local Time has only ~4 useful times: dawn, daytime, dusk, & nighttime. Where I grew up, the parks closed at dusk every day. Nobody complained

If I take a walk at 7:05:35 PM every day, it seems very precise but doesn't indicate whether I need sunglasses or a flashlight. It's meaningless precision, like 0.6235 slices of pizza. If I'm coordinating a walk with you, I might as well use UTC: it still won't tell light from dark, but at least nobody'll be waiting for an hour due to DST. It'd make more sense to schedule our walk at `1 hour before dusk`, or "just" settle for UTC, IMO.
