Android time server

---

I running an app which synchronizes with a remote server (for more details, it´s called: “Notepad”).

But there is a difference between the app-server time, and my phone time. And this difference is > 1 minute, so I am getting a synchronization warning from the app.

¿How does my phone know what time is it?
¿Does it uses a time server from Google on the Internet or it uses the mobile network?
¿Which server is that (in order to query by NTP)?

It uses your mobile network, but only if your network supports it and network sync is enabled in the settings.

The built-in clock of your phone "drifts" quite a lot (seconds per day). If the system time is important to you it might be a good idea to sync it with a time server regularly.

ClockSync can do it for you. You can choose the time server yourself. Your phone needs to be rooted to make it work, because for some reason Google is very anal retentive about the time settings.
