there can be other problems. I had a machine be OK, and then started
to be out by minutes/hr for about a year. I corrected with a Hz
setting in the ntp.conf file. Then suddenly it was OK again. This was
about 10yrs ago. I didn't change any hardware. I never found the problem.

Guy (and hopefull girls),
This has nothing to do with LVS and/ or heartbeat. I guess you are
running a Linux guest within a Linux host vmware server (or ESX)? If so,
there are known problems with clock fluctiations in guests VM's.
We run our Development servers on VMWare ESX and GSX and had large clock
fluctuations. The VMWare TID's weren't directly much helpfull in solving
the problem.
How we fixed it:
- vmware-linux-tools are not helpfull in solving this problem. You don't
need them to fix thr time issue
- On the VMWare Server management console webinterface, go to Options ,
Advanced Settings, and search fro the option Misc.TimerHardPeriod.
Default value is 1000 , adjust it to 333.
On the linux guest machine:
-For Grub edit: /boot/grub/menu.lst add "clock=pmtmr" to add the end of
your current kernel and reboot.
-For Lilo edit: /etc/lilo.conf and add to the append rule of your
current kernel "clock=pmtmr". Run lilo and reboot.
-This should fix your problem (run ntpd on both host and guest OS, no
vmware-tools)
