This is an atomic clock that is synchronized with a time server using the ntp protocol. The time server can be selected by the user.
This is a precise implementation of a NTP client with packet round-trip time in order to assess the tolerance of the displayed time.
A main feature is the fine-trim to a local comparison clock.
It is very hard to read fractions of a second.
However, it is very easy to determine the synchronization of two clocks to a few hundredth of a second. You hereby receive an exact time difference of the local clock.
