This SHOULD work if you use your BIOS setup and ***REMEMBER TO SET IT TO
UTC*** 

If it does not, my guess would be that you have a hardware problem.  

Likewise, you should be able to do a set the date with the date command,
and then do a 

clock -uw

to set the hardware clock.  RedHat has no manpage for this command, I just
happened to remember the command from Slackware.  The -u says use UTC
time, and the -w says write the system time to the hardware clock.

RedHat also has the hwclock command, but I think it requires more typing
and is much less simple than the clock command.
