Sometimes in Windows you need to change the current date value, for example, to correct the document creation time or to fix a system crash. This can be done using standard system tools.
How to change the date in Windows XP
Double-click on the clock icon in the tray (bottom right corner of the screen). To change the month, in the properties window that appears in the "Date" section, click on the down arrow to the right of the field that contains the current month and select a new one. The year can be changed by clicking the up and down arrows to the right of the corresponding field. To select a date, click on the desired date.
Due to complex processes in the electronic devices of a computer, the system time begins to diverge from the real time. You can get rid of the discrepancy if the computer is connected to the Internet. Go to the "Internet Time" tab, check the box next to the "Synchronize" item and click OK.

You will need administrator rights to change this setting. Click on the clock icon and follow the link "Changing the date and time settings". In the Date and Time window, click the Change Date and Time button. In the Date field, change the current value using the right and left arrows.
Perhaps the date is getting lost because the time zone is incorrectly selected. Click the Change Time Zone button and select your location from the list. To synchronize the system timer with the world time, go to the Internet Time tab.
