ABSTRACT:
Time messages are transmitted from a central timebase to a local timebase. The transmission time of a time message is detected and is entered as a data value in a subsequent time message. The reception time of a time message is detected, and the transmission time contained in it is reproduced, by the local timebase. Finally, the difference between associated transmission and reception times of time messages is used to determine the time discrepancies occurring in the process, and these are evaluated for synchronization of the local timebase.
