If you can't change the time or time zone on your Apple device
You can use Date & Time settings to have your device adjust automatically for time zone changes and daylight saving time. If the wrong date, time, or time zone appears on your device, or if it doesn't automatically adjust for daylight saving time, learn what to do.
Set the date and time automatically
Follow these steps to make sure that your device is able to set the time and time zone automatically. (The option to set the date and time automatically might not be available on all devices.)
iPhone, iPad, Apple Vision Pro
Make sure that your device is connected to the internet.
Install the latest software updates for your device:
Open Settings. Tap General, tap Date & Time, then turn on Set Automatically. This automatically sets your date and time based on your time zone. Is this setting dimmed?
If a message says that updated time zone information is available, restart your device and any paired Apple Watch.
Open Settings. Tap Privacy & Security, tap Location Services, scroll to the bottom and tap System Services, then turn on Setting Time Zone. This allows your device to use its current location to determine the correct time zone.
Mac
Make sure that your Mac is connected to the internet.
Open Location Services settings and make sure that 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 that the settings for time zone and system customization are turned on.
Open Date & Time settings and make sure that the option to set time and date automatically, as well as the option to set time zone automatically, are both turned on.
Restart your Mac.
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 that your Apple TV is connected to the internet.
Open Settings, select General, then scroll down to the Date & Time section and turn on Set Automatically. If it’s already turned on, turn it off and back on. If a message says 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 Date & Time settings. If the message appears now, restart your Apple TV to get the update.
Set the date and time manually
If your device still shows an incorrect date, time, or time zone, change each setting manually instead of using Set Automatically.
iPhone, iPad, Apple Vision Pro
Open Settings. Tap General, tap Date & Time, then 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 that you need.
Or tap the date to change the date and time.
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.
Apple TV
Open Settings, select General, then scroll down to the Date & Time section and turn off Set Automatically.
Open Settings, select General, select Time Zone, then choose a time zone.

The option to turn Set Automatically on or off might not be available with all carriers or in all countries and regions. If the device has a Screen Time passcode or a corporate profile with device restrictions installed, the setting might be dimmed (grayed out).
If the time on your device is wrong after you sync it with your Mac, make sure that Date & Time are set correctly on your Mac.
Making manual adjustments to time settings in order to change app behavior (like game timers) isn't recommended.
