They are separate controls: the clock can be accurate for the wrong zone, or the zone can be right while the displayed time is wrong. Follow the steps for your device, then use the troubleshooting checks below if it still shows the wrong local time.
First, identify what is wrong
Compare the device with a reliable local clock and check its displayed time zone. If the time zone is wrong, correct that setting rather than simply changing the hour. A named regional time zone applies the location’s daylight-saving rules; a manually entered time or UTC offset may not.

- Wrong clock time: check automatic date and time.
- Wrong time zone: check automatic time zone or select the correct zone manually.
- Both are wrong: enable or correct both settings.
Automatic time-zone detection may depend on internet access, location permissions, device or carrier capabilities, and operating-system support. Menu names can also vary by device.

Fix the setting on your device
iPhone or iPad
- Connect to the internet and install any available iOS or iPadOS updates.
- Open Settings > General > Date & Time and turn on Set Automatically.
- For location-based time-zone selection, open Settings > Privacy & Security > Location Services > System Services and turn on Setting Time Zone.
- If the device says its time-zone information was updated, restart it. Restart a paired Apple Watch as well.
If automatic settings still choose incorrectly, turn off Set Automatically and select the correct time zone by city, or set the date and time manually. Apple says the automatic option is not available for every device, provider, country, or region; Screen Time restrictions or a corporate profile can also make it unavailable or greyed out. See Apple’s date and time guidance (published January 27, 2026).

A greyed-out control does not necessarily mean the clock is broken; a restriction or device policy may be controlling it.

- PLUG IN ALARM CLOCK WITH BATTERY MEMORY: This plug in alarm clock powered by USB only — all functions, including the display, require a wired power connection.

- Apple devices: Screen Time restrictions or a corporate profile may prevent changing automatic settings. Check the applicable restriction or ask the organization that manages the device.
- Windows: Microsoft says non-administrator users cannot change or interact with automatic time-zone settings in certain Windows 10 configurations. Organizational policy may also control them. Ask the computer’s administrator or IT support to check policy and location permissions. Do not edit registry or Group Policy settings on a managed device without administrator guidance. See Microsoft’s explanation of unavailable automatic time-zone settings.
What to check if the clock still has not updated
- Recheck both controls. Confirm whether the time, time zone, or both are wrong, and enable the matching settings separately.
- Reconnect and check permissions. Restore internet access and allow location access if the device uses location to detect its time zone.
- Install available operating-system updates. Updated time-zone data can matter when regional rules change; restart afterward if the device maker recommends it.
- Use a manual regional zone if needed. Select the correct zone by city or region rather than changing only the hour or relying on a UTC offset.
- Check for management restrictions. If a control is unavailable or greyed out, ask the device administrator or IT support rather than trying to bypass policy.
When a government changes time-zone or daylight-saving rules, devices may need updated time-zone data. Microsoft says rule changes are incorporated through Windows Updates and recommends that governments provide “one year or more” notice before planned changes. That guidance does not establish whether a particular local rule is already reflected on an individual device. See Microsoft’s daylight-saving time support guidance.
