You can use the "zdump" to verify the DST rules. Substitute the right
timezone in the command below:
$ /usr/sbin/zdump -v "US/Pacific" -c 2006,2008
US/Pacific Fri Dec 13 20:45:52 1901 UTC = Fri Dec 13 12:45:52 1901 PST
isdst=0 gmtoff=-28800
US/Pacific Sat Dec 14 20:45:52 1901 UTC = Sat Dec 14 12:45:52 1901 PST
isdst=0 gmtoff=-28800
US/Pacific Sun Apr 2 09:59:59 2006 UTC = Sun Apr 2 01:59:59 2006 PST
isdst=0 gmtoff=-28800
US/Pacific Sun Apr 2 10:00:00 2006 UTC = Sun Apr 2 03:00:00 2006 PDT
isdst=1 gmtoff=-25200
US/Pacific Sun Oct 29 08:59:59 2006 UTC = Sun Oct 29 01:59:59 2006 PDT
isdst=1 gmtoff=-25200
US/Pacific Sun Oct 29 09:00:00 2006 UTC = Sun Oct 29 01:00:00 2006 PST
isdst=0 gmtoff=-28800
US/Pacific Sun Mar 11 09:59:59 2007 UTC = Sun Mar 11 01:59:59 2007 PST
isdst=0 gmtoff=-28800
US/Pacific Sun Mar 11 10:00:00 2007 UTC = Sun Mar 11 03:00:00 2007 PDT
isdst=1 gmtoff=-25200
US/Pacific Sun Nov 4 08:59:59 2007 UTC = Sun Nov 4 01:59:59 2007 PDT
isdst=1 gmtoff=-25200
US/Pacific Sun Nov 4 09:00:00 2007 UTC = Sun Nov 4 01:00:00 2007 PST
isdst=0 gmtoff=-28800
US/Pacific Mon Jan 18 03:14:07 2038 UTC = Sun Jan 17 19:14:07 2038 PST
isdst=0 gmtoff=-28800
US/Pacific Tue Jan 19 03:14:07 2038 UTC = Mon Jan 18 19:14:07 2038 PST

You can see DST takes effect on March 11 this year, so the rules are
updated. This output was from a CentOS 4 system, but I'd imagine the
results should be the same on CentOS 3.
