ABSTRACT:
The invention relates to a method for synchronizing computer clocks in networks used for the transmission of information according to which information is dispatched with a time stamp when being dispatched and which is re-transmitted with a time stamp in a confirmation of receipt. The time stamps are inserted in the outgoing or arriving data packet by a clock module (8) mounted downstream of a network controller (4, 10) once said network controller has authorized transmission. A CPU (2) generates actuator signals that are provided with an identifier and that correct the clock modules (8) on the basis of a comparison between the time stamps in a confirmation of receipt of the addressee of the information and the time stamp of the corresponding transmitted information.
