1 hour is easy to remember, makes the math easier, and not so far apart that it creates radically different concepts of time for people on the extreme ends.

With one hour time zones:

* If someone is 3 time zones ahead, they're 3 hours ahead

* There are 24 time zones and 360 degrees neatly divides by 24

* 2 hours between time zones means that within a time zone, the sun rises on one side at 8 am and on the other side at 10 am.

We have :30 and :45 time zones though, no :15 time zone. So that doesn't quite apply.

Doesn't it?

I was explaining why 1 hour as the standard makes sense instead of 30 minutes or 2 hours. The :45 time zones would still be an issue for 30 minute intervals and :30 and :45 are still an issue for 2 hour intervals

But the 1 hour is not a standard, we have many places with :45 and :30 time zones. For example, Newfoundland is -3:30 time zone. Nepal is in a +5:45 time zone.

Again, I never said it was the standard. I was saying why 1 hour offsets make more sense than 15 minutes or two hours. I never said different offsets don't exist, I said why they make less sense

And those exceptions demonstrate why it's a bad idea to go beyond hour offsets. It's just added hassle.
