Date & Time
In the App list, click "Settings"
to open the system setting app, and select
the option "Date & time".
If you enabled the option "Automatic date & time" under "Date & time",
system date and time will be synchronized automatically with network time
when you connected a Wi-Fi network.
If you want to set the time manually, you need to disable "Automatic date &
time" and "Automatic time zone".
