Timers of a plurality of slave units are synchronized with a timer of a master unit by a) sending a synchronization message on the first network by the master unit, which contains a time measurement of the master unit and a time scale, to the slave units; b) at each slave unit, forming the difference between a time measurement recorded in the slave unit and the time measurement received by the master unit, and correcting the current time measurement of the slave unit by this difference, and, at each unit, the recording of a time measurement upon receipt of the time scale; c) at the master unit, inserting the recorded time measurement into a subsequent synchronization message.
