Claim:
1. A method comprising: receiving, at a first hardware device, a time synchronization message from a remote second hardware device in a Data Over Cable Service Interface Specification (DOCSIS) Remote Physical layer (R-PHY) network; determining a time difference between a first clock at the first hardware device and a second clock at the second hardware device from the time synchronization message; re-stamping an event message based on the time difference; receiving, at the first hardware device, a Media Access Protocol (MAP) message from the second hardware device; identifying a stitch point in the MAP message; and modifying the MAP message at the stitch point based on the time difference, wherein the modifying comprises adding a MAP timing unit at the stitch point if the clock drift indicates that an under-run threshold is crossed.
