title: Is Android using NTP to sync time?
body: <p>Do Android Devices use the network time protocol (NTP) to synchronize the time?</p>
  
  <p>In my Device-Settings I see a checkbox with the following text "synchronize with network", but I don't know if they are using NTP.</p>
  
  <p>I need this for my Bachelor Thesis for which I use GPS. To get an accurate GPS-signal the receiver should have an exact clock.</p>
  
  <p>I have found this blog-entry on the web, but I'm not sure if he tells the truth: <a href="http://kousik.blogspot.de/2012/02/speeding-up-ntp-gps-lock-in-android.html" rel="noreferrer">Speeding up NTP, GPS Lock in Android</a></p>
