As long as your Android is connected to a wireless or Wi-Fi signal, it will automatically update its internal date, time, and time, all for Daylight Savings and more. These automatic changes can be enabled or disabled from your Android settings and, if it is disabled, you can change everything manually.
First, you need to find your Android date and time settings.

Open the Clock app for your Android. If you have a clock widget on your Home page, you can open the Clock app by clicking on the current time.
In the Clock app, tap the three dots in the upper right corner.
Click Change date and time to open Android Date and time settings.
To turn automatic updates on or off, click Set time to automatically update.
If you disable Set time to change, you can manually change the date and time on your phone by clicking the Date and Time options, respectively. As long as the switch is off, it can’t be changed to whatever is assumed to be local time. Remember, at the end of Daylight Savings, set your clocks back one hour.
