Did ancient people know about what we would today call “time zones?” And if so, could they prove it?

If they knew the earth rotated, then they could assume that noon happened at different times at different locations. But did they have a way to prove this without being able to travel or communicate fast enough to observe the effects?

They were likely aware of the concept but would not have been able to prove it definitively. That’s where the true rub of the question is. As a similar point, it was KNOWN the Earth was round well before the age of exploration, but it was not PROVEN until Magellan’s fleet circumnavigated the globe.
