To synchronize your computer's clock with an Internet time server

When you synchronize your computer's clock with an Internet time server, the clock on your computer is updated to match the clock on the time server. This helps make sure that the clock on your computer is always accurate. Your computer's clock is typically synchronized with the Internet time server once a week but your computer must be connected to the Internet for the synchronization to occur.

If your computer is on a domain, you can't synchronize your clock with an Internet time server. Instead, you need to change your computer's date and time manually. To do this, follow the steps under "To change your computer's date and time" above.

If your computer is not on a domain, follow the steps below to synchronize your computer's clock with an Internet time server.

  1. Click the Start button Picture of the Start button, click Control Panel, click Clock, Language, and Region, and then click Date and Time.
  2. Click the Internet Time tab, and then click Change settings. Administrator permission required If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

  3. Click Synchronize with an Internet time server, select a time server, and then click OK, and then click OK again.
