NTP Clock

Turn your Windows Mobile device into a very accurate clock.

NTP Clock is a Simple Network Time Protocol (SNTP) client which uses NTP or SNTP time servers on the internet or your local LAN to compute the current time. These servers maintain time with a very high accuracy, sometimes with an error of just a few microseconds. NTP Clock uses the information it receives from these servers to compute the current time as well as the offset between the "NTP clock" and the "device clock". With a reasonably fast network connection, such as Wi-Fi or LTE/4G, an accuracy of a few milliseconds is typically achieved.


  • Analog or digital clock displays.
  • Display clocks in local time or UTC.
  • User-configurable list of NTP servers.
  • The NTP protocol details view displays the contents of the response from the NTP servers. This can be useful for simple debugging of NTP servers.
  • No ads.
  • No data harvesting.
