I think William is referring to this:
http://lists.centos.org/pipermail/centos/2006-February/060651.html
I successfully use "clock=pit" on i686 environment on a lot of
CentOS4.3 and RH9 inside CentOS4.3 installs. However, it still
requires the vmware-tools to have been installed and the "Sync
to Host Clock" option has been clicked.

Here's a possibility:
- Copy the vmware tools ISO image out of the VM Host onto the
the Guest. It is found in "/usr/lib/vmware/isoimages/linux.iso"
- mount the ISO loopback and copy the RPM/tarball into /tmp/ - unmount
- install the VMware-Tools RPM/tarball
- run vmware-config-tools.pl (no gui needed).
- *don't forget* - edit your Guest VM /etc/grub.conf to add
the "clock=pit" (I keep forgetting on new VMs I create...)
- shutdown your guest.
- Now on your HOST, edit your guest's .vmx file and change the
line from:
tools.syncTime = "FALSE"
to "TRUE". In mine, it's the last line in the .vmx file.
I sure wish this could be done from the VMware Server Console...
- Fire up the guest and run for cover!
I have not tried this, I just poked around trying to figure out
what that check-box was causing to change. Worst case, you
need to tunnel X through an SSH login from a remote system
with an X display and check the checkbox in vmware-toolbox
from there...
Do *NOT* run NTP in the VMware Guest. The basic clock in
the VM isn't precise enough and you'll never get synchronization.
NTP is to add accuracy to a reasonably precise but not
necessarily accurate clock source. However, it cannot fix
an "insane" time-source. You definitely want to run NTP on
your VMware Host, though.
Best of luck,
