How Time Sync Works in an Active Directory Domain?
In the Active Directory environment, the time synchronization is performed according to a typical domain hierarchy:
Primary Domain Controller Emulator (PDC) is the main time source in the domain. PDC can synchronize its time with the local hardware Complementary Metal-Oxide-Semiconductor (CMOS) clock (default) or with an external NTP source in the parent domain.
In the Root domain, other Domain controllers synchronize their time with Primary Domain Controller Emulator (PDC) of parent domain.
The PDC emulator in the child domains synchronize its time with the PDC or any other domain controller from the parent domain.
Other domain controllers can synchronize time with PDC Emulator from own domain or any other domain controller from parent domain.
Workstations and member servers synchronize their time by any domain controller in its own domain.
