By default, Android devices rely on their network providers to provide the correct time. Android devices also rely on your network provider to determine which time zone you are in. Your network provider tracks your location and updates your time zone when you travel. This is how your device usually displays the correct time.
If your service provider is in trouble or you lose network while traveling, you may find yourself showing the wrong time. Your device doesn’t have to rely on your network provider to tell you the time. It can also be set to different time zones without tracking your location. To do this, you can manually set your time and time zone. Here’s how to manually change the time and time zone on your Android device.
You can change the time on your Android device through the Settings app or through the Clock app. Let's take a look at both procedures.
Open the Clock app on your device and tap the three-dot menu icon in the top right corner.
