A method for synchronizing the operating clock and the timing clock of a subordinate domain (236) of an automation network, wherein sync slaves (218,224,230) are synchronized by a clock sync master (200) with respect to an operating clock (216), a clock sync master (206) forms part (200) of a subordinate domain, a single synchronization message (212) serves to synchronize the sync slaves with respect to their respective operating clock (216) and timing clock (204), wherein the method comprises providing a notification of the difference (214) between the timing clock (204) and the operating clock (216) using the synchronization message, and accepting this difference (214) into the synchronization message (212) as additional information.
