I have 2 DC's. One is virtual, one is physical. The time on my domain is running fast. I suspect this is due to one of the DC's being virtual.

How can I set the domain to use the physical DC as the time master?

Edit: I mean the domain time is in sync, all DC's & all work stations have the exact same time. However the time is fast compared to an accutate time source for comparison (ie Cell phone), so today it's 30min fast, tomorrow it's 35min fast, the day after 40min, etc.

You should transfer the PDC emulator FSMO role to the physical domain controller.

This is done by opening the Active Directory Users and Computers snap-in on the physical domain controller (or by specifically targeting it). Right click on the domain itself, choose operations masters, and transfer the role.

Then you should follow this: http://technet.microsoft.com/en-us/library/cc786897(v=ws.10).aspx

and point that PDC emulator DC to NIST, or Microsoft, or Apple or whoever you want as your time source.

Once this is done, all other domain controllers will sync to the time on the DC with the PDC emulator role, and workstations will sync to whichever domain controller responds to the SRV record lookups.

Other good reading (yes, you really should read it):
