The fastest way to change your iPhone's time

Open Settings, tap General, then tap Date & Time. Toggle off the switch next to Set Automatically if it is on. The time field will become editable — tap it and use the scroll wheels to set the hour, minute, and AM or PM. When you are done, toggle Set Automatically back on, or leave it off if you want to keep manual control.

If Set Automatically is already off, you can jump straight to tapping the time field and adjusting it. The whole process takes about 30 seconds.

Your iPhone will also ask you to confirm your time zone while you are in this menu. Make sure it matches where you are, because the phone uses it to calculate the correct time even when Set Automatically is on.

Key Takeaways

  • Go to Settings > General > Date & Time and turn off Set Automatically to edit the time manually.
  • Use the scroll wheels in the time field to set the hour, minute, and AM or PM to whatever you need.
  • Your time zone setting controls what time your phone shows, so check it is correct for your location.
  • You can leave Set Automatically off permanently if you prefer to control the time yourself, though most people turn it back on after making a one-time change.
  • If your phone keeps changing the time back, Set Automatically is still on — toggle it off again and make sure it stays off.

Why your iPhone might show the wrong time

If Set Automatically is on, your iPhone pulls the time from your cellular network or Wi-Fi connection. If you travel across time zones or your phone loses signal, it may take a few minutes to update. If you are in an area with poor coverage, the phone might hold onto an old time until it reconnects.

If Set Automatically is off and you have not changed the time recently, someone else may have adjusted it, or your phone may have been reset. Check the time zone setting too — if it is wrong, the time will be wrong even if the clock itself is set correctly.

Turning Set Automatically back on

Once you have set the time manually, you usually want to turn Set Automatically back on so your phone stays in sync with your network. Go back to Settings > General > Date & Time and toggle the switch on. Your phone will fetch the correct time from your carrier or Wi-Fi within a few seconds.

Leave it off only if you have a specific reason to keep the time fixed — for example, if you are testing an app that depends on a particular time, or if your network time is consistently wrong in your area.

What to do if the time keeps changing back

If you set the time manually but it reverts to a different time a few minutes later, Set Automatically is still on. Go back to Settings > General > Date & Time and make sure the toggle is fully off — it should be gray, not green. Tap it once more if you are unsure.

If the toggle is already off and the time is still changing, restart your iPhone. Hold the power button until you see the power-off slider, swipe it, wait 30 seconds, then hold the power button again until the Apple logo appears. After the restart, check the time again.

Changing the time zone without changing the time

If you only want to change your time zone — for example, because you moved or traveled — go to Settings > General > Date & Time and tap the time zone field. Search for your city or the region you are in. Your iPhone will automatically adjust the displayed time to match the new zone, even if Set Automatically is on.

If Set Automatically is off, changing the time zone will not change the time you see on the clock — only the time zone label will update. This is rarely what you want, so turn Set Automatically back on after you change zones.

When to call Apple Support

If your iPhone time is wrong and toggling Set Automatically off and on does not fix it, or if the time keeps jumping around even after a restart, contact Apple Support. The issue may be a software glitch that needs a full reset, or a hardware problem with the phone's clock chip.

Before you contact them, write down exactly what is happening — for example, "the time jumps back 2 hours every 10 minutes" or "the time is stuck 3 hours ahead and will not update." This detail helps them diagnose the problem faster.

Frequently Asked Questions

Can I set a different time on my iPhone than what my carrier shows?

Yes. Turn off Set Automatically and set any time you want. Your iPhone will keep that time until you turn Set Automatically back on or manually change it again. The carrier time does not override your choice once you have disabled automatic updates.

Does changing the time affect my alarms or reminders?

Yes. If you set your iPhone to a time earlier than it actually is, alarms and reminders scheduled for the real time will go off sooner than you expect. Always turn Set Automatically back on as soon as you are done testing, or set the time back to the correct time before you rely on alarms.

What if I do not know my time zone?

Go to Settings > General > Date & Time and tap the time zone field. Type your city name or the name of the nearest major city in your region. Your iPhone will show matching results — pick the one that matches your location. If you are unsure, search for "time zone" plus your city name in a web browser first.

Will changing the time drain my battery?

No. Changing the time or time zone uses almost no battery. If your battery is draining fast, it is not because of the time setting — look for apps running in the background or a screen brightness that is too high.
