1. Open System Preferences and then click the Date &
Time icon.
You can also open the Date & Time control panel by clicking-and-
holding the clock in the upper-right corner of the screen and then
choosing Open Date & Time from the contextual menu that appears.
2. Click the Clock button to bring Clock preferences to the
front, as shown in Figure 1-19.
3. Select Use a 24-Hour Clock to display time in 24-hour
format.
If you’re displaying time in 24-hour format, it makes sense to
deselect the Show AM/PM option.
4. Adjust other clock options as desired and then click the
Date & Time button to show the calendar and time set-
ting options, as shown in Figure 1-20.
Some clock options — such as Analog display — aren’t compati-
ble with a 24-hour clock.
5. If you want the computer to automatically synchronize
its clock with an online date and time source, make sure
that Set Date & Time Automatically is checked. Choose
a source based on your geographical location.
