Abstract
Techniques for correcting time synchronization inaccuracy caused by asymmetric delays on a communication link. Time synchronization according to the present techniques includes determining an asymmetry in a propagation delay on a communication link used by a first device and a second device to exchange timing information and incorporating the asymmetry into a determination of a clock offset between the first and second devices.
