As a time connoisseur, I really get really pissed off when my phone's time is off by a second or two. Considering phone receives time from the radio network, one would expect this not to happen. However, for some reason, it seems no USA network provider actually cares to have their radio time straight. The solution to this problem would be using an NTP server instead of the time provided by the network. However, with an Android devices that's not as straightforward as one would expect. But it is possible...
Before starting anything, we first need to turn on Developer Options (usually tapping Build Number 7 times). Once this is enabled, we need to enable USB Debugging (Settings > System > Advanced > Developer Options > USB debugging). With this done, we can finally download Platform Tools and check if our device is visible:
List of devices attached
Once connectivity is tested, we can immediately go onto setting the NTP server followed by a reboot:
adb shell settings put global ntp_server time.medo64.com
Once device has rebooted we can check the value:
adb shell settings get global ntp_server
And that's it. Now your device will use the defined time server instead of the unreliable network time.
