Time Zone, Server Clocks, VMWare, Virtual Machines.

Here is the problem Occasionally say once a month or so, the Domain controller clocks, (and the all the Server Clients and Workstation CLients) adjust their system time by 3 hours (moves forward).
So if the server is in the eastern time zone, and this issue occurs, the clock will move forward by 3 hours. If its suppoed to be 8:00 PM Pacific, it will show 11:00 PM, for eastern the same thing.
The only way to fix the issue is to restart the windows time service on all domain controllers. The issue only seems to affect the VM Domain Controllers
This causes logins to the domain to intermittently fail, once the time service is restarted on all the domain controllers, then the tiume corrects itself and the (logon issue) goes away.
What I have checked so far:
1) All servers have the correct time zone set, for the timezone the server is physically in.
2) None of the servers (domain controllers) are syncing their time to the VMWare host
3)The NTP servers for each of the Windows Domains (there are many windows domain that this same issues occurs on) - are all correct and the time service is working.
Any ideas? on this? I really dont understand what is happening here. When the issue occurs every domain controller, regardless of timezone has its clocks moved forward by 3 hours.
