Changing Your System Date and Time

by Allen Wyatt
(last updated August 10, 2015)

Your computer uses an internal clock that keeps track of both the date and current time. Windows relies upon this clock and works closely with it. For instance, when Windows saves a file, the current date and time are saved with the file. If the date and time are wrong, then it means that the wrong information is saved with those files.

Normally you don't need to worry about changing the date and time; Windows updates them automatically over the Internet. However, if your computer is not connected to the Internet, you may need to change the date and, particularly, the time. You can make your own changes in this manner:

  1. Click once on the date and time in the Notifications area at the right side of the Taskbar. Windows displays a calendar and clock.
  2. Click the Change Date and Time Settings link. Windows displays the Date and Time dialog box. (See Figure 1.)
  3. Figure 1. The Date and Time dialog box.

  4. Click Change Date and Time. Windows displays the Date and Time Settings dialog box. (See Figure 2.)
  5. Figure 2. The Date and Time Settings dialog box.

  6. If you want to change the date, click a new date in the calendar.
  7. If you want to change the time, use the digital clock control (under the "wall clock" display) to enter a new time.
  8. Click OK to close the Date and Time Settings dialog box.
  9. If you want to change the time zone in which your computer is located, click the Change Time Zone button. Windows displays the Time Zone Settings dialog box. (See Figure 3.)
  10. Figure 3. The Time Zone Settings dialog box.

  11. Use the Time Zone pull-down list to select the appropriate time zone.
  12. Click OK to close the Time Zone Settings dialog box.
  13. Click OK to close the Date and Time dialog box.
