Well, I should not have used Pacific-New in the first place. Guy Harris gave
this detailed answer:

Err, umm, *not*.
"tzsetup" only chooses the time zone that's stuck into the kernel for
the benefit of:
1) pre-SunOS 4.0 binaries;
2) old programs written to the old pre-4.0 BSD time zone
interface and not fixed to use "timelocal()" or "mktime()" to
convert from local time to UNIX time;
3) *new* programs unfortunately written to the old BSD time
zone interface, the fact that they were written for SunOS 4.x
nonwithstanding, and not fixed to use "timelocal()" or
"mktime()" to convert from local time to UNIX time (e.g.,
Calendar Manager.
"date" is not one such program; it uses the new time zone stuff. If
it's reporting PPET, that's the time zone you have set up on your
machine.
(PPET is, in fact, one of the time zones for which no old-style time
zone type is completely valid, so "tzsetup" isn't *capable* of choosing
PPET.)
It sounds as if somebody set up "US/Pacific-New", rather than
"US/Pacific", as your time zone. "Pacific-New" is described in the
comment in "/usr/share/lib/zoneinfo/pacificnew":
# From Arthur David Olson (April 5, 1989):
# On April 5, 1989, the U. S. House of Representatives passed (238-154) a bill
# establishing "Pacific Presidential Election Time"; it has yet to be acted on
# by the Senate or signed into law by the President.
# You might want to change the "PE" (Presidential Election) below to
# "Q" (Quadrennial) to maintain three-character zone abbreviations.
# If you're really conservative, you might want to change it to "D".
# Avoid "L" (Leap Year), which won't be true in 2100.
and no, at least according to today's paper, it still hasn't been acted
on by the Senate, or still hasn't been signed into law by the President;
this is a Presidential election year, but the clocks got turned back at
2AM last night, rather than staying on Daylight Savings Time until after
the election.
Try becoming super-user and doing
zic -l US/Pacific
and then rebooting; that should put you back on normal Pacific time.

--------------------------------------------------------
other solution:
cd /usr/share/lib/zoneinfo
mv -f localtime localtime-
ln US/Pacific localtime
date /* you should have PST instead of PPET */
/* and your time should be correct now */
You have to have access as 'root'.

I used the "zic" method and everything is fine.
