Why is having fewer time zones a good thing?

Wouldn't this actually be confusing, because things would have to be happening at different local times depending on where you are in the time zone?

I wasn't really advocating for it, I just think if we were crazy enough to adopt this time system, 10 time zones would also be a necessary adjustment.

Ah, I see. That makes sense! Although not all timezones are +/- an integer number of hours.

This is already the case, timezones have weird shapes and some of them are huge.

In Europe and China you have timezones spanning over 3 "sun" timezones. In practice that means the sun rising and setting at different times. People are used to have the sun setting late or rising early depending where they live.
