Not exactly. Sort of. Phoenix and Denver are both in America/Denver (aka US/Mountain), but only Denver observes DST. San Francisco and Los Angeles are both in America/Los_Angeles, and both observe DST. > At least the US has governed DST transitions.

Way back in the 1990s, I was working with teams in Metro Chicago, Tel Aviv, and Tokyo (three separate teams, three really separate time zones, at least two seaprate DST transition dates). I changed my wristwatch to 24 hour time (and never looked back). I tried UTC for a while, which was cute, but confusing. -- https://mail.python.org/mailman/listinfo/python-list
