Stephen,
This comes up quite often so let me help. First there are two
clocks; system clock and hardware clock.
The one we tend to know about is the system clock and we invoke the
date & time with the command; date
The one we tend to not know about is the hardware clock. To see the
hardware clock time use any one of the following:
hwclock
hwclock -r
hwclock --show
If you are in a Red Hat Linux environment in addition to the above
the commands;
clock will also work - (it does not work in Debian Linux.)
So first set your system clock to get it exactly like you want it,
the syntax is;
MMDDhhmm[[CC][YY].[ss]]
MM = the month 03 for March
DD = the day of the month today 28
hh = the hour of the day right now about 06
mm = the minute of the hour right now about 29
CC = is optional, the century 20
YY = is the year, now 01
. = is the separator between YY and the seconds
ss = is the seconds of the minute
The things in [] are all optional
Now to force the hardware clock time to be the system clock time do
either:
hwclock -w
OR
hwclock --systohc
Should you want to force the system clock to be that of the hardware
clock do either:
hwclock -s
OR
hwclock --hctosys
You can also set the hardware clock directly with the following
syntax;
hwclock --set --date="03/28/01 06:29:00"
I recently became a Linux Professional Institute Certified
(LPIC)Systems Engineer and this is the kind of information they want you to
know about to pass the exams - hard work but very enjoyable.
Join the discussion group; [EMAIL PROTECTED] as that is a
fine group to be associated with. A couple of key players and class
act people are Dan York and Chuck Mead.
Also consider the LPI program as I think it is going to become the leader in
Linux certification.

John D. Holp

You're in Central USA, aren't you? :)
... which means your timezone is GMT -6 hours!
This is no coincidence. When you installed you probably told it to set
your clock to GMT/UTC. When you do this, the hardware clock is set to
GMT and linux adds/subtracts the amount of time specified in your time
zone file for use as the system clock. That's why your clock is 6 hours
behind.
You can either:
1. leave UTC set to yes, set your clock to GMT/UTC
2. set UTC to no and set your clock to localtime
Option 1 is the best option if your system doesn't dual boot with
Windows. Otherwise use option 2.
Matthew
