the general rule of thumb for American Timezones is that Arizona is its own special thing and as long as you stay out of that state then you're in America/{los_angeles|denver|chicago|new_york} for pacific, mountain, central, and eastern respectively.

Just stay away from Arizona and American time zones are easy and what you did would work.

Arizona is special because it's in mountain time, it doesn't observer daylight saving time so half the year it has the same time as pacific time except for the Navajo Nation which does observe daylight saving time but the Hopi Nation which is entirely inside the Navajo Nation doesn't follow daylight saving.
