Abstract:
1. An arrangement for transferring a time of day value from a first network element to a second network element via a data communications network wherein a first phase reference signal is available to the first network element and a second phase reference signal, which is phase locked relative to said first phase reference signal, is available to the second network element, the arrangement including: in said first network element, a first processor unit which is arranged to create a difference variable that is adapted to indicate the difference between the timing phases of said time of day value and said first phase reference signal and to write said difference variable in a data unit which is to be sent to said second network element, and in said second network element, a second processor unit which is arranged to read said difference variable from said data unit and to create an estimate of said time of day value based on said difference variable and the timing phase of said second phase reference signal.
