Yeah, tbh the "no timezones" approach comes with its own basket of problems that isn't necessarily better than the "with timezones" basket. The system needed to find a balance between being useful locally, but intelligible across regions. Especially challenging before ubiquitous telecommunications
Imagine having to rethink the social norms around time every time you travel or meet someone from far away. They say "Oh I work a 9-to-5 office job" and then you need to figure out where they live to understand what that means. Or a doctor writes a book where they recommend that you get to bed by 2:00PM every night, and then you need to figure out how to translate that to a time that makes sense for you.
We'd invent and use informal timezones anyway, and then we'd be writing Javascript functions to translate "real" times to "colloquial" times, and that's pretty close to just storing datetimes in UTC then translating them to a relevant timezone ad hoc, which is what we're already doing.
That's what my rational programmer brain says. My emotional programmer brain is exactly this meme.
My emotional brain thinks we should just give up and climb back into the trees.
Funny enough, a story just broke about a lunar timezone, which would lose a second or so every year relative to Earth due to relativity. If space travel becomes a big thing we're going to have to choose a frame of reference, and probably just go with Unix epoch in that frame as the universal time. Hopefully it doesn't happen to pass through a black hole, because there's no consistent way to define a frame of reference that's not subject to gravity.
