The tzdata updates will *REPLACE* changed tzdata files. So, the
current tzdata files for US/Paficifc will reflect the new timezone
rules. Your TZ value remains the same - at least in this TZ change
case. It's possible and conceivable that governments can and will
create new timezones that have different rules from any existing
timezones, which would require the creation of a new TZ value.

Interesting to note how often DST/timezome changes happen around the
world by looking at the tzdata package changelongs. Personally, I
think DST is bogus.
