Will changing the time zone manually also change the clock?

Yes. Selecting a different time zone under Time zone ➔ Region shifts the displayed time to match that zone, even if the actual local time is different.

Can I set the time zone without a working data or SIM connection?

Yes. Manual time zone selection works offline since it does not rely on network data. You still need to navigate through Settings ➔ System ➔ Date & time to make the change.

What happens to existing alarms and calendar events after changing the time zone?

Alarms set as fixed clock times stay at that same clock time in the new zone. Calendar events tied to a specific time zone may shift, so check any entries created while automatic detection was on.

How do I go back to automatic time zone detection later?

Return to Settings ➔ System ➔ Date & time and turn Set automatically back on. Android will then follow the network-reported zone again.

Android: Change the Time Zone Manually

When your phone joins a network in a different region, the time zone updates on its own and can throw off calendar entries, alarms, and reminders. Sometimes automatic detection picks the wrong zone, or you just want a fixed setting no matter where you are. Turning off automatic detection lets you lock in the time zone you actually need.

Change Time Zone Manually auf Android

Android pulls the time zone from the mobile network by default. That works fine while you stay in one region, but it can cause problems when you travel, use a foreign SIM, or connect to a network that reports the wrong location.

Wrong time zones affect more than the clock. Calendar invites shift, alarms fire at the wrong hour, and app timestamps no longer match reality. Switching to a manual time zone stops the system from overriding your setting every time the network changes.

How to set the time zone manually

Open Tap on Settings ➔ Tap on System ➔ Tap on Date & time. Turn off Turn off Set automatically to disable network-based detection.

Then tap Tap on Time zone ➔ Tap on Region ➔ Select the Region ➔ Select the Time zone to pick the exact zone you want.

Keep in mind that with automatic detection off, the time zone stays fixed even if you travel. If you cross zones often, switching automatic detection back on is usually the better fix.

Frequently asked questions

If Set automatically is still turned on, Android reapplies the network-reported time zone whenever you connect to a different carrier or Wi-Fi network. Turn it off under Settings ➔ System ➔ Date & time to keep your manual choice.
