Time Service Core

The Time Service Core component synchronizes a workstation's clock with other computers using the Network Time Protocol (NTP) version 3. For increased accuracy, this component also incorporates algorithmic enhancements from NTP 4.

In a Windows 2000 or Windows XP domain, this component will automatically synchronize the time with a domain controller. The network time samples are authenticated using the NetLogon secure channel. If your time source becomes unavailable, this component will dynamically discover a new source of time.

This component allows you to synchronize your clock from a variety of hardware clocks using extensible add-in provider architecture. This allows you to keep accurate time using a variety of clocks, including Global Positional System (GPS) clocks and cesium clocks.

You can use the W32tm.exe tool to override the default settings or if your computer is not connected to a domain.
