Just a question on the time service


If I manually move a member servers time to 2 hours in future.    Should it return to same time as the pdc (which is the time source )

With out using the resync command.  


It doesn’t (waited 12 hours )


Everything set as default.

Depends on how often the system is set to resynchronize with the master.  Most are set to resynchronize once a day, so it could take up to 23 hours and 59 minutes.

I find it prudent to set systems to resynchronize at least twice a day, and I feel that three times is better.  If you run your own time server there's no reason to not resync every four hours -- though the additional accuracy is negligible, it defends against systems that have dead RTC batteries.

The resync interval is set in the Registry.  There may be a GPO setting related to it, but the Registry setting is what the system uses.

Now there is some discussion about whether this actually works on later revisions of Windows.  Personally I have found it to work as advertised, but some claim it does not.
