Abstract: A slave node calculates and stores a propagation delay generated when exchanging a message with a master node. The master node transmits a reference time indicated by a hardware clock of the master node, and the slave node synchronizes a hardware clock of the slave node to the reference time indicated by the hardware clock of the master node. The master node transmits a time value in a first time domain to the slave node, where the time value is calculated by the master node by adding an offset of the first time domain to the reference time. The slave node calculates the offset using the time value and the stored propagation delay, and obtains a time in the first time domain by applying the calculated offset to a reference time indicated by the hardware clock of the slave node.
