Although I remember the clock=pit part of that, and the divider=10 piece.... But I remember a couple of years ago reading the opposite about NTP.... Oh well, just goes to show that best practices change, although I have had fairly good results from VMware with the VMware tools sync, where I did not at that time have good results with NTP in the guest. On ESX 3.0.x and later ESX 3.5. Well, time to go redo some things, I guess. We have a GPS-disciplined physical box as one of the three NTP masters we use....
