You're assuming an awful lot about me based on complete ignorance and using those assumptions to justify a really bizarre level of abuse.

You don't understand time zones or geopolitical history either it seems, and you're imaging people from thousands of years ago to have a concept of universality.

I'm not. That's literally the premise of the idea proposed here. The fact that you don't get that is really making me question your reading comprehension abilities.

You're not proposing a single improvement,

Correct. I'm not. As I've noted several times now, I'm not proposing anything. I'm just pointing out that we have a significant bias toward the system we already know.

Except it is, because that's how hours work. You probably don't know where they come from either

Yeah, they were chosen more or less arbitrarily by the ancient Egyptians because there were twelve significant constellations they followed, which led to a sort of base-12 number system they used for stuff related to the sky (months and hours in particular).

Again, units and numbers have no inherent meaning. We made it all up. A day could just as easily have had ten hours of 144 minutes each, or 40 hours of 36 minutes each.

I know it seems to you like you're making sense, but you're not...

The fact that you don't understand what I'm saying doesn't mean that I'm not making sense. And I think there's ample evidence here that you're just not reading carefully.

...because you're ignorant of so many assumptions you've made, which if changed, would be like giving ancient Romans the GPS instead of them using sundials and that said Romans would've magically been able to consider that theyre noon is two hours after "the real" noon, which is based on.........?

Ok. Deciphering your word salad here, I think you're trying to suggest that our current 24-hour day and time zones were somehow inevitable? Which...I mean, obviously they aren't, since there are many cultures that independently came up with different time systems.

There's a Hindi clock that divides the day into thirty hours. Roman timekeeping was divided into 12 hours, but that time was measured from sunrise to sunset. Byzantine time uses the same division of days into 24 hours, but starts a day at sunset, meaning that the start of a day changes within the same city throughout the year. France even tried decimal time for a while, where each day has ten hours, each hour has 100 minutes, and each minute has 100 seconds. All of these systems arose from different starting conditions, none of which were "giving Romans GPS" (they already knew the Earth was round) and none of which caused any problems with users going to sleep at different times of day.

The thought experiment here isn't "how could this have happened given existing conditions?" or even "what conditions could have brought this about?" but rather "assuming a world where some set of conditions brought about a true worldwide UTC without offsets, what would it look like to the users of that system?"

And this is what you've decided merits abusive behavior. Can't imagine what you're like about stuff that actually matters.
