Dell computers use Windows operating systems, which enable you to perform a variety of functions. The built-in clock on your Dell computer enables you to record the time you install applications, modify files and folders, or create new files. It also comes in handy when you want to use system features such as System Restore. If your clock is out of sync, you change the time and time zone quickly and easily anytime you want.
Click the Windows "Start" button, click the "Control Panel," and then click "Clock, Language, and Region." Click "Date and Time."
Click the "Date and Time" tab and click the "Change date and time" option. If prompted, type your administrator password and click "OK."
Locate the "Date and Time Settings" section and double-click the hour to change it. Click the up or down arrow keys to change the hour value. To change the minutes, double-click the minutes, and then click the up or down arrow keys to change the minutes value. To change the seconds, double-click the seconds, and then click the up or down arrow keys to change the seconds value.
Click "OK" to save the changes when you finish adjusting the time. Click the "Change time zone" button if you want to change the time zone. Select your current time zone in the "Time Zone Settings" dialog box, and then click "OK."
Synchronize the Windows clock with the Internet time server, if you like. Performing this action matches your clock to the time server to ensure that your Windows clock is accurate. To synchronize the Windows clock with the Internet time server, click the "Date and Time" option in the "Clock, Language, and Region" section, click the "Internet Time" tab, and then click the "Change Settings" option. If prompted, type your administrator password and click "OK." Click the "Automatically synchronize with an Internet time server," select the server, and click "OK" to save the changes.
