How to Change an iPhone Clock Displayby Steve Gregory
Glancing at your iPhone’s clock is a convenient way to track the time, especially if you don’t wear a watch. If you are accustomed to a 24-hour clock, however, it can become a bit annoying to keep looking at the iPhone’s default 12-hour clock display. Like many of the iPhone’s other features and utilities, you can configure the clock display. The option to convert the clock to the 24-hour format is on the device’s Time and Display screen.
Select the "Settings" icon on your iPhone's home screen to display the Settings menu.
Select "General" from the list of options to open the General screen.
Select "Date and Time" to open the Date and Time screen.
Tap the "24-Hour Time" ON/OFF switch to the "ON" position. The clock immediately changes to the 24-hour time format.
- To change the clock's time zone, open the Date and Time screen. Tap the "Set Automatically" ON/OFF button to "OFF," and then tap "Time Zone." Enter your location -- such as a city -- in the Search box. Select the name of your location from the list of results.
- To manually set the date and time, tap the "Set Automatically" ON/OFF button to "OFF" on the Date and Time screen. Use the controls to set the date and time, and then tap the "Date and Time" button.
