Changing the system tray clock from 24 to 12 hour format

To change the time format in the system tray clock can be challenging. Click Start | Control Panel. If you’re in XP native view, click “Date, Time, Language and Regional Options.” If you’re in Classic view, click Regional and Language Options. Click the Customize button, then click the Time tab. In the drop down box for Time Format, choose h:mm:ss tt or hh:mm:ss tt. The “tt” stands for A.M./P.M. The selections that begin with capital H cause the clock to display military (24 hour) time.
