Time Difference on Servers and Workstations

Today I noticed there is a 5 minute gap between my Active Directory controller time that has the PDC role and all the computers joined to the Active Directory domain. When I run the command "net time" on a child server/workstation, they properly report the time on the domain controller with the PDC role.

The domain controller that has the PDC role is a physical machine and we do have a secondary domain controller that is virtualized in a Hyper V environment.

Any idea whats causing the time sync to be off?"
 
check the system event log one of the workstations and see if there's any errors from the Time-Service source

I see this "NtpClient was unable to set a domain peer to use as a time source because of DNS resolution error on ''. NtpClient will try again in 3473457 minutes and double the reattempt interval thereafter. The error was: The requested name is valid, but no data of the requested type was found. (0x80072AFC)."

The last time that showed up was 10-12-2012, so not sure if that is still valid or not. Ill see if I can find out what not resolving or wasn't resolving in DNS for that specific error.

EDIT:

When I issue the w32tm /query /source command, it shows the secondary domain controller that doesnt have the PDC role. Shouldnt this be the DC with the PDC Role? Whats also weird, if I do a net time, it does show the proper domain controller with PDC.

are there any just informational events logged, which would say the time sync was successful?

how about if you do a:
w32tm /resync /nowait

then check system event logs again and see if it was an informational or error logged for the time-service source.

theoretically, any DC should be able to provide a response to an NTP request.
The rest of the DCs just query the one running the PDC emulator to sync, but are supposed to be able to be a time source for workstations.
