Internet time servers keep your Windows clock up to date and almost perfect with international standards. Vista has 4 preset Internet time servers, one hosted at Microsoft. To synchronise, you need an Internet connection at any speed.

1. Click once on the clock in the notification area of your taskbar.
2. Click on Change date and time settings.
3. On this new dialog, select the Internet time tab, then click Change settings.
4. Tick the first box on the screen, then select the Update now button to update your time.

   If one sever doesn’t work, then try selecting a different server from the drop down menu.

5. Once it works, it’ll tell you that your time has been updated.
6. Close all your open windows.
