FYI: If you still haven't patched your VMware ESX servers, here is a quick and easy way to patch, no rebooting necessary.

VMware ESX 3.0.1 servers, built from the 3.0.1 CD, do not need to update. Please use the zdump command to verify.

This procedure will help you to manually modify the /etc/localtime, just execute the following:

(First of all, check the time zone in the following file
/etc/sysconfig/clock)

1- Check zoneinfo file has the correct change dates:
# zdump -v /usr/share/zoneinfo/ |grep 2007

for example:
# zdump -v /usr/share/zoneinfo/US/Pacific |grep 2007

2- Check /etc/localtime for the same:
# zdump -v /etc/ |grep 2007

3- They were different, so executed zic to update it:
# zic -l /usr/share/zoneinfo/

Check again using the step 2.

If this command doesn't work just copy the desired time zone file to /etc/localtime.
cp /usr/share/zoneinfo/ /etc/localtime

For example:
cp /usr/share/zoneinfo/US/Pacific /etc/localtime

I would like further information about using ESXUPDATE to update for the
