Abstract
A method, at an egress node, includes synchronizing with a global reference time; receiving a signal including a presentation time for when a specific part of the signal is to be transmitted, wherein the presentation time was determined by the ingress node with reference to the global reference time; determining an actual transmission time when the specific part of the signal is transmitted; and causing adjustment of a clock based on a time error derived from a difference between the presentation time and the actual transmission time.
