Where to find the clock settings on Android

The clock on your Android phone lives in the system settings, not in the clock app itself. Open Settings, then look for System or About phone — the exact path depends on your phone's manufacturer. Samsung phones often label it General management instead. Once you find the right section, look for Date and time.

If you cannot find it by scrolling, use the search box at the top of Settings. Type "date and time" and Android will show you the exact location on your phone. This is faster than hunting through menus, especially on phones with many customization layers.

Key Takeaways

  • The clock setting is in Settings > System > Date and time (or Settings > General management > Date and time on Samsung phones).
  • Turn off Automatic date and time before you can manually change the time yourself.
  • After you change the time, you can turn automatic sync back on so your phone stays correct without your help.
  • If your phone keeps resetting the time to the wrong value, your carrier or network may be overriding your choice — contact them to check.

Turning off automatic time sync so you can change it manually

By default, Android syncs your clock to your carrier's network time automatically. This keeps your phone accurate without you doing anything. To change the time yourself, you must first turn this off. In the Date and time menu, look for a toggle labeled Automatic date and time or Use network-provided time, and switch it to off.

Once you turn off automatic sync, two new fields appear: Set date and Set time. These are now clickable. Tap each one to enter the correct values. The date field usually opens a calendar picker; the time field opens a clock dial where you can spin the hours and minutes to the time you want.

Changing the time zone separately from the clock

Android separates time zone from the actual time. You can change one without changing the other. In the same Date and time menu, you will see Time zone as a separate setting. Tap it to see a list of all time zones, organized by region and city. Find your location and tap it.

If you turn automatic time zone on, Android will update it based on your location when you travel. If you turn it off, you can set it manually and it will stay put. Most people leave automatic time zone on and only manually set the clock time when it drifts.

What to do if the time keeps changing back

If you set the time manually but it resets to a different value within minutes or hours, your phone is likely still syncing to the network despite the automatic setting being off. This happens on some carriers and corporate networks. Check the Date and time menu again — if the automatic toggle has turned itself back on, your network is forcing it.

Contact your mobile carrier to ask whether they lock the time setting on your account. Some carriers do this for billing and network reasons. If they confirm they are overriding your choice, you may not be able to change it without switching carriers or using a workaround like a third-party clock app (though the system time will still be controlled by the network).

Using a third-party clock app if you need a different display

The system clock and the clock app are separate. Changing the system time in Settings affects when your phone thinks it is — this controls your alarms, calendar, and timestamps on files. A third-party clock app from the Google Play Store only changes what you see on the home screen or lock screen, not the actual system time.

If you want a different clock style or format on your home screen, read a clock widget or app. But understand that the system time underneath is still what you set in Settings. If you need the actual system time to be different, you must change it in Settings, not in an app.

Changing the time format from 12-hour to 24-hour

In the Date and time menu, look for Time format or Use 24-hour format. Toggle it to switch between 12-hour (with AM and PM) and 24-hour (military time). This only changes how the time is displayed — it does not change the actual time on your phone.

This setting affects clocks throughout your system: the lock screen, status bar, alarms, and calendar. Some apps may ignore this setting and show their own format, but most system apps respect it. If you change your mind later, you can switch back at any time.

When to call your phone manufacturer or carrier

If the Date and time menu is missing entirely, or if the toggles are grayed out and you cannot change them, your phone may be managed by an organization (your employer, school, or carrier). Contact the IT department or support line that manages your phone — they have set a policy that locks these settings.

If the time keeps resetting despite automatic sync being off, and your carrier says they are not forcing it, the problem may be a software bug or a hardware issue with your phone's real-time clock. Restart your phone first. If the problem persists, contact your phone's manufacturer support line and describe exactly what happens and how often.

Frequently Asked Questions

Will changing the time affect my alarms or calendar events?

Yes. If you set the time backward, alarms and events scheduled before the new time may trigger when ready or skip entirely. If you set it forward, alarms scheduled soon may be delayed. Change the time only when necessary, and check your alarms and upcoming events afterward to make sure they are still correct.

Can I change the time on my lock screen without changing the system time?

No. The lock screen shows the actual system time. If you want a different clock style or size on your lock screen, you can use a custom lock screen app or widget, but the time displayed will still be the real system time. To change what time is shown, you must change the system time in Settings.

What does "automatic date and time" actually do?

It syncs your phone's clock to your mobile carrier's network time server. This keeps your phone accurate without you having to adjust it manually. When you turn it off, your phone uses only its internal clock, which may drift slightly over time. Most people leave it on and only turn it off temporarily if they need to set a custom time for testing or troubleshooting.

Why does my phone show a different time than my computer or watch?

Each device has its own clock. If they are out of sync, check whether automatic time sync is on for each device. Computers and phones may also be set to different time zones. Open the Date and time menu on your phone and verify the time zone matches your location, then check the same on your computer. If both are set correctly and still disagree, one of them may have a hardware clock that is drifting.
