Follow these steps. After each step, see if you still need help:
- Make sure that you have the latest version of iOS.
- Turn on Set Automatically in Settings > General > Date & Time. This will automatically set your date and time based on your time zone and your device will let you know if there’s a time zone update.
- Make sure that your time zone is set correctly. Tap Settings > General > Date & Time > Time Zone.
If you still have issues setting your date, time, or time zone, you can turn off Set Automatically in Settings > General > Date & Time and manually set the time and time zone. You should only manually adjust the date and time on your device if it isn’t set correctly and doesn’t update automatically. Manually adjusting the date or time on your device to change app behavior, for example game timers, isn't recommended.
The option to turn on Set Automatically might not be available with all carriers or in all countries.
If the time on your iOS device is wrong after you sync it with your computer, your computer's time might be wrong. Check the time on your computer in System Preferences > Date & Time. You might want to select "Set date and time automatically."
