Dear David,
I’ve had similar problems in the past with VMs running SLES.

Subject: VM time sync issue
Hi all - somewhat gory one here so deep breath...
All our VM(ware) hosts are time sync'd to a physical NTP server.
Does anyone else have their IdP on a SLES v10 or 11 VM? Ours is 4 minutes faster than a Windows VM on the same farm (but different hosts), but 4 mins out is failing the security check on an SP - that's if I have vmtools refreshing the time on the VM to be the
same as the host it's running on.
I've tried disabling the vmtools sync, and relying on NTP, but whilst that helped initially it drifted to make the IdP 5mins ahead of the SP. It's affecting one of our external services as well (which has a fussier tolerance on time differences).
I've also tried the advice here:
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1006427
But when I put in the kernel parameters it came up with an error on reboot saying it couldn't find the path to clock or hpet.
Any advice appreciated - our VMware admin is off today so sadly I can't double check things right now.
Thanks,
Dave
