switch to/from Daylight savings doesn't happen

Hi,

FreeBSD 4.5 doesn't seem to auto-switch to/from DST at the right
time.

----------%<----------%<----------%<----------%<----------%<----------

# setenv TZ :/usr/share/zoneinfo/America/Los_Angeles

# /bin/date
Tue Oct 25 15:40:10 PDT 2005
 
# /bin/date 200510300159
Sun Oct 30 01:59:00 PST 2005  <-- should be PDT ?

----------%<----------%<----------%<----------%<----------%<----------

Oct 30, 1:59 falls under PDT, instead `date` command returns PST.
I am sure I have the right tzfile.

The following change in date.c seems to fix the problem; the PDT->PST
switch happens automatically at oct 30 2.00am. Not sure if that's the
way to fix it.


Index: date.c

Thanks,
Prakash
