  • How often do clients update time from PDC emulator?

    Does anyone know how often do clients update time from the PDC emulator when joined to a domain?

    Thanks

      Don't know if this will help

      How Windows Time Service Works

      There is also this one

      Basic operation of the windows time service

      Which states

      Code:
      2. Polling Loop
      
      a.  The client contacts an authenticating domain controller. Packets are exchanged to determine the latency of communication between the two computers. 
       W32Time determines what current time should be converged to locally, (the "target" time). 
       
      b.  The client adjusts the local time. If the target time is ahead of local time, local time is immediately set to the target time. 
       If the target time is behind local time, the local clock is slowed (slewed) until the two times are aligned, unless local time is more than 3 minutes out of synchronization, in which case the time is immediately set. 
       
      c.  The time server client performs periodic checks. The client connects to the authenticating domain controller once each "period." 
       The initial default period is 45 minutes. 
       
      d.  If the time synchronization attempt is successful three consecutive times, then the interval check period is increased to 8 hours. If it is not successful three consecutive times, then it is reset to 45 minutes.
