If you can’t change the time or time zone on your Apple device
You can use Date & Time settings to enable your device to adjust the date and time automatically following time zone or clock changes. If the wrong date, time or time zone appears on your device, or if it doesn’t adjust for clock changes automatically, find out what to do.
Set the date and time automatically
The option to set the date and time automatically may not be available for your device.* Follow these steps to make sure your device is able to set the time and time zone automatically.
On your iPhone or iPad
Make sure you have the latest version of iOS or iPadOS.
Turn on Set Automatically in Settings > General > Date & Time. This sets your date and time automatically based on your time zone. Is this setting dimmed?
If a message appears saying that updated time zone information is available, restart your device and any paired Apple Watch devices.
Allow your device to use its current location to determine the correct time zone. To do this, go to Settings > Privacy & Security > Location Services > System Services and turn on Setting Time Zone.
Check that your device is using the correct time zone in Settings > General > Date & Time > Time Zone.
On your Mac
Make sure your Mac is connected to the internet.
Open Location Services settings and make sure Location Services is turned on. Then scroll to the bottom of the list of apps and services and click the Details button next to System Services. Make sure "Time zone and system customisation" is turned on.
Open Date & Time settings and make sure the option to set time and date automatically, as well as the option to set time zone automatically, are turned on.
Restart your Mac.
On your Apple TV
These steps require tvOS 10 or later on Apple TV HD or Apple TV 4K. If you’re using an older version of tvOS or an older Apple TV, you can set the time zone manually.
Make sure your Apple TV is connected to the Internet.
Go to Settings > General > Time Zone. If a message appears saying that updated time zone information is available, restart your Apple TV to get the update.
If the message doesn’t appear, press and hold the Back button
or the Menu button on your Apple TV remote to go to the Home Screen. Wait several minutes, then return to Settings > General > Time Zone. If the message now appears, restart your Apple TV to get the update.
Set the date and time manually
If your device is still displaying an incorrect date, time or time zone, change each setting manually instead of using Set Automatically. For example, you may have iOS 9 or earlier, and your country or region or government has subsequently changed time zones or the observance of clock changes.
On your iPhone or iPad
Go to Settings > General > Date & Time.
Turn off Set Automatically. Is this setting dimmed?
Change the time zone or the date and time:
Tap Time Zone and enter a city with the time zone you need.
Or tap the date to change the date and time.
On your Mac
Open Date & Time settings and turn off the option to set time and date automatically, as well as the option to set time zone automatically. You can then set time, date and time zone manually.
On your Apple TV
Go to Settings > General > Time Zone.
Make sure that Set Automatically is turned off, then choose a time zone.

If the time on your device is wrong after you sync it with your computer, make sure Date & Time are set correctly on your Mac.
Manual adjustments to time settings to change app behaviour (such as game timers) aren’t recommended.

* The option to turn Set Automatically on or off may not be available with all network providers or in all countries and regions. If the device has a Screen Time passcode or a corporate profile with device restrictions installed, then the option to turn Set Automatically on or off will be dimmed or greyed out.
