If you change the face style to digital, you also have the option of a 12-hour or 24-hour clock. The default is a 12-hour Clock, which has an A.M. or a P.M. printed next to it. The 24-hour Clock uses military time. For instance, 1:00 P.M. is displayed as 13:00. Figure 7-7 shows both the 12-hour and the 24-hour clocks.
