I wasn’t introducing north south timezones, just reacting to the common issue that is that some countries prefer summer time, while others prefer winter time. The issue seems to be there because we want countries as far apart as Spain and Poland to share the same timezone.

An article that addresses that issue, with an interesting proposition (4 timezones instead of 3)

the US work with different timezones

Timezones solve an entirely different problem.

I think that technically, time zones may include whether-or-not DST is supported, not just the “bands”. But, okay, yeah, that’s semantics.

That being said, the US also doesn’t entirely use daylight savings time, so @[email protected]’s point still stands.

https://en.wikipedia.org/wiki/Daylight_saving_time_in_the_United_States

Most of the United States observes daylight saving time, the practice of setting the clock forward by one hour when there is longer daylight during the day, so that evenings have more daylight and mornings have less. Exceptions include Arizona (except for the Navajo, who do observe daylight saving time in Navajo Nation),[1] Hawaii,[2] and the overseas territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the United States Virgin Islands.

North south timezones also dont work all that well really. the further you go both morning and evening move. so you just end up having to got to work in the middle of the night and come back in daylight or the other way round
