I’m afraid ACPK is correct, timezones are quite a bit more complicated than you’re making it out to be.

If you take a peek into the IANA TZ database, you’ll see many, many timezones in play in the US alone. Not all of them are currently relevant (eg Indiana).

A breakdown of timezones by region worldwide can be seen here: http://efele.net/maps/tz/world/

Arizona, for instance, does not follow DST but the Navajo land inside of it does.

This also ignores the fact that many states have been trying to permanently set themselves to DST. This is much more likely to change in the near future than the US adding a new state, so caching such information in the same file could be problematic.

Thank you for this @mshafrir
