You can also double-click on the clock in the lower-right corner of your desktop or taskbar to display the Date/Time properties dialog box and change time settings.

How To Fix Date / Time Problems
When you boot the PC press F2 to get into the system BIOS to see what the system date & time are set to. If that is correct go into Windows and get into Date & time and check that you are set for the right time zone as well.
Sometimes Date and Time get lost or don’t run when you shut down. The system clock, while turned off, is maintained by the CMOS battery on the motherboard. They usually last for a quite a few years, but it could be that the battery has gone flat. It's just an ordinary watch battery (those 1.5V flat disc batteries) so should be quite easy to find. Replace it and see if it helps.
