Confirm my system needs a tzdata update:
[root@myth ~]# zdump -v /etc/localtime | grep 2007
/etc/localtime Sun Apr 1 09:59:59 2007 UTC = Sun Apr 1 01:59:59 2007 PST

Apr 1 is not correct for 2007.

[root@myth ~]#
---------------------------------------------------
Confirm fix:
[root@myth ~]# zdump -v /etc/localtime | grep 2007
/etc/localtime Sun Apr 1 09:59:59 2007 UTC = Sun Apr 1 01:59:59 2007 PST
isdst=0 gmtoff=-28800
/etc/localtime Sun Apr 1 10:00:00 2007 UTC = Sun Apr 1 03:00:00 2007 PDT
isdst=1 gmtoff=-25200
/etc/localtime Sun Oct 28 08:59:59 2007 UTC = Sun Oct 28 01:59:59 2007 PDT
isdst=1 gmtoff=-25200
/etc/localtime Sun Oct 28 09:00:00 2007 UTC = Sun Oct 28 01:00:00 2007 PST
isdst=0 gmtoff=-28800
Hrm, still not right. Tried a reboot, but didn't help. Then found:
http://kbase.redhat.com/faq/FAQ_85_9951.shtm
The following confirms that localtime hasn't been updated:
[root@myth ~]# ls -l /etc/localtime
-rw-r--r-- 1 root root 1017 May 7 2005 /etc/localtime
Do I have the time/date control panel? (yes)
[root@myth ~]# which system-config-date
/usr/bin/system-config-date
[root@myth ~]# date
Thu Mar 1 00:44:54 PST 2007
Run the control panel gui (must be in X windows to use this tool):
[root@myth ~]# system-config-date
(This runs the timezone control panel in X11/gui. Don't need to change anything, just click the OK button and /etc/localtime will be updated automatically.)
Now /etc/localtime has been updated:
[root@myth ~]# ls -l /etc/localtime
-rw-r--r-- 1 root root 1017 Mar 1 00:45 /etc/localtime
Now zdump confirms the correct (new) DST rules are in effect:
[root@myth ~]# zdump -v /etc/localtime | grep 2007
/etc/localtime Sun Mar 11 09:59:59 2007 UTC = Sun Mar 11 01:59:59 2007 PST isdst=0 gmtoff=-28800
/etc/localtime Sun Mar 11 10:00:00 2007 UTC = Sun Mar 11 03:00:00 2007 PDT isdst=1 gmtoff=-25200
/etc/localtime Sun Nov 4 08:59:59 2007 UTC = Sun Nov 4 01:59:59 2007 PDT isdst=1 gmtoff=-25200
/etc/localtime Sun Nov 4 09:00:00 2007 UTC = Sun Nov 4 01:00:00 2007 PST isdst=0 gmtoff=-28800
Now restart all processes that are date sensitive (mythbackend!)
Done!
