the unified chronometer. How it all started. Wempe Chronometerwerke faced new political and economic challenges in the years prior to the Second World War and during the early years of the conflict. The business was stripped of its independence and subordinated to the ministries of the navy and air force in 1939. The sharp increase in the demand for precision instruments for warships and submarines impelled both ministries to order ever-greater numbers of chronometers from Wempe, where production was correspondingly increased. Demand was so strong that Wempe Chronometerwerke was ultimately unable...

WEMPE NTP-Server The NTP-Server provides a service for time Synchronisation on the Ethernet. Unlike usual time protocols the Local Time Server does not emit UTC, but LT. The server itself gets its time from a main clock that provides the time format LT or the difference to UTC. The server is intended to be connected to a HU20097 main clock or as an extension for the UTC-related NTP of the HU20100 main clock. Connected computers can thus get the current local time set on the main clock from the Local Time Server via NTP service. The server is connected to the main clock by means of a serial interface....
