Fundamentally, this requires knowledge of timezone data. That means
you have to select a political time zone, which basically means you
want the Olsen database (tzdata) which primarily works with city
names. I'm not sure whether "US/Pacific" is suitable; I usually use
"America/Los_Angeles" for Pacific US time.

But that aside, what Gary said is what I would recommend.
