Q. How can I get accurate time on an Android device?
A. The best way to get accurate time on an Android device is via GPS or NITZ (cell provider).
The GPS satellites send out very good time every second.
You can't always get it indoors.
If your device doesn't have cell or GPS (eg a tablet) then you can use NTP
(Network Time Protocol) over the Internet.
Its available in Settings.
