vmware timekeeping

[Jeff Dickens]

I'm running FreeBSD 6.3-release as a guest on VMware ESX 3.0.2.  My 
problem is that the clock keeps *gaining* time.  I have the "timesync" 
option turned on in ESX's .vmx file, and I have "hint.apic.0.disabled=1" 
in my FreeBSD guest's /boot/loader.conf.

I used to have "kern.hz=100" in loader.conf, but that caused the guest 
to gain time even faster.

Does anyone have a good recipe for decent timekeeping in this config?

Thanks.
