Abstract

A method for operating a node in a communications network comprises the following steps: The node receives a reference time via the communications network. A transmit clock of the node, which was determined for an earlier clock cycle on the basis of a local clock of the node, is compared with the reference time. The local clock of the node is corrected on the basis of the comparison result. On the basis of the corrected local clock a transmit clock is determined to be used by the node for the current clock cycle.
