[ILUG] [Slightly OT]VMWare Server/Client Time Sync

[Hamilton, David (TSG C&I)]

I have a Fedora 8 server running VMWare server and have a problem with the time in one of my VMs.
I run a WinXP VM for certain tasks which I don't like the Linux tools for.
This guest was running fine, as far as I know anyway, but a bit slow, so I changed it to having 2 CPUs.
The time on the VM now runs in double time, so the drift is somewhat spectacular.
I do have the 'stnc time with host' option set, but I don't know how often that kicks in.
Has anyone had this kind of behaviour?
Any ideas on a fix?

Thanks,
        David.
