Windows Vista Computer losing time

Your Windows Vista computer is able to synchronize its clock with a time server on the Internet. But if you find that your computer time isn't right, maybe you need to change your time server. Here's how you do it:

• Click Start and then click Control Panel
• In the Control Panel, click the Classic View link on the left side of the Window
• In the Classic View Control Panel Window, double click the Date and Time icon.
• In the Date and Time dialog box, click the Internet Time tab.
• On the Internet Time tab, click the Change Settings button.
• Click Continue in the User Account Control dialog box.
• In the Internet Time Settings dialog box, click the Server down arrow and select another time server. The default is time.windows.com. Try using time.nist.gov first and see how that works for you.
• Click OK in the Internet Time Settings dialog box.
• Click OK in the Data and Time dialog box.
