Abstract
The present disclosure generally relates to systems and methods for estimating and compensating clock period drift of a hardware clock of a node in a timing network. In some implementation examples, a node generates a plurality of time stamps based on a plurality of synchronization signals received from an upstream node according to the hardware clock, where each of the plurality of time stamps records a point in time at which each of the plurality of synchronization signals is received according to the hardware clock. The node selects two subsets of time stamps from the plurality of time stamps, and then selects one time stamp from each of the two subsets based on a curve that fits time stamps in each of the two subsets. The node calculates an estimated period of the hardware clock based on two time stamps selected.
