Which would make scheduling Zoom meetings or even just phone calls hell.

Especially when everyone's half-hour blocks are misaligned with each other's so you can't even stack meetings efficiently.

And public transport timetables, which were the original reason timezones were introduced in the first place.

This is why I think we should entirely ditch the concept of timezones. Clock time, as we use it, is largely decoupled from solar time anyway, and all attempts to reconcile the two just lead to confusion.

We already have terms a few terms to tie events to solar time, for example, a park being open from dawn to dusk. And without time zones, we might come up with a few more.

I figure everyone would just use local time locally, and unadjusted UTC for everything else.
