If you are running Windows XP or Vista, you’ll never have to worry about manually setting your computer’s clock again! Of course, you have to be online for this little trick to work, so keep that in mind.
For Windows XP: Just double-click the little clock in the System Tray and it will bring up the Time and Date Properties screen. Click the Internet Time tab and you’ll see a button that lets you instantly synchronize your clock with one on the internet.
For Windows Vista: Just click the clock in the system tray once to bring up the time. At the bottom of the box is says Change Time and Date Settings. Click on that, and then on the Internet Time tab and then the Change Settings box.
In both cases, you’ll notice that there’s a check box that says “Automatically synchronize with an internet time server.” If you uncheck that box, you won’t be able to do a manual synchronization. However, with this feature enabled, not only can you do our little trick, but your computer will automatically update its time once a week – all by itself.
Anyhow, no matter how it gets updated (manually or automatically), it’s still a handy way to keep your computer’s clock right on time.
