Abstract
The invention relates to a method for synchronizing a first clock C to a reference clock A, the first clock C being connected to said reference clock A via a processing unit B. The invention moreover relates to a processing unit B and to a synchronization system. In order to enable a synchronization of said first clock C to said reference clock A via said processing, unti B. it is proposed that the processing unit B generates a correction message cmsg for the first clock C based on timestamps exchanged between the processing unit B and the reference clock A, which exchanged of timestamps is triggered by clock pulses cclk received in the processing unit B from the first clock C.
