A note by Johnny Hughes in http://bugs.centos.org/view.php?id=2189
(comment 6644):

"As a side note ... if the clock GAINS (runs to fast) time you should
be able to fix it with this:

http://kb.vmware.com/kb/1591

(by setting the correct host.cpukHz) and vmware tools should adjust a
clock that is too slow.

Also see this blog entry concerning host.cpukHz:
