Changing the Date and Time

Windows depends on accurate system time. Use Control Panel’s Date and Time utility to adjust your system’s clock, set its time zone, or turn on Internet-time synchronization.

To set the date and time:

In Control Panel, choose Date, Time, Language, and Regional Options > Date and Time.

On the Date & Time tab (Figure 4.48), adjust the date and time as needed.

Figure 4.48. To set the time in the Time box, type new numbers; press the up- and down-arrow keys; or click the small up and down arrows.

On the Time Zone tab (Figure 4.49), select your time zone in the list.

Figure 4.49. The map is decorative; you can’t click your location to specify your time zone.

Windows assumes that you do want to Automatically Adjust Clock for Daylight Saving Changes. Uncheck this box if you don’t want to use daylight saving time.

On the Internet Time tab (Figure 4.50), check the Automatically Synchronize With an Internet Time Server box to synchronize your computer clock with a highly accurate time server. Once a week is the only interval you get unless you click Update Now.

Figure 4.50. You can type the address of any time server in the Server box. Microsoft operates time.windows.com; the U.S. government operates time.nist.gov. Your network administrator or computer’s manufacturer may have included other time servers in the list.

Click OK (or Apply).


  • When your computer is shut down, its internal battery maintains the system clock.

  • Internet-time synchronization occurs regularly only if you have a full-time Internet connection, such as DSL or a cable modem. If you use dial-up, click Update Now while you’re connected to the Internet to synchronize your clock immediately.

  • A time server won’t adjust your computer’s clock unless your PC’s date is set correctly.
