This app shows the current exact atomic time of PTB in Braunschweig. In addition, the deviation of the device time from the exact time is determined. And all this with a single click - no frills around it.
A New Year's Eve countdown can also be activated.

Two operating modes can be selected:
* Running clock: A continuously running clock is displayed, the comparison with the atomic clock is carried out automatically at regular intervals.
* Time snapshot: The current atomic time at the moment of synchronization is displayed as a template to e.g. to put other clocks.

The app remains on the screen even after the phone returns from energy saving mode (e.g. used as a regular clock during meetings).

The date and time zone (the latter based on the phone settings) are also displayed.

Different background colors or images can be selected.

All 3 PTB NTP time servers are queried so that an atomic time is practically always available.
