Time Service Advertisement

Applies To: Windows Server 2008 R2

The Windows Time service (W32time) provides time source advertisements that clients can use to synchronize their clocks. The Windows Time service on a domain controller can be configured as either a reliable or an unreliable time source. The Windows Time service running on a client will attempt to synchronize its time source with servers that are indicated as reliable. The Windows Time service can configure a domain controller within its domain as a reliable time source, and it synchronizes itself periodically with this source.
