i believe that US/Pacific is a commonly used alias for America/Los
Angeles. i can't find a definitive source for this, but the w3c note
on time zones (<http://www.w3.org/TR/2005/NOTE-timezone-20051013/>)
mentions tz aliases.

reading over the wikipedia page on time zones
(<http://en.wikipedia.org/wiki/Time_zone>) and several linked pages,
it looks like most computer systems do in fact use olson, but some
augment or replace the "canonical" olson tzids with more familiar
aliases like US/Pacific.
