Classification: CPC H | IPC H

Claim 10:
11. A method of operating a network node of an area network, the method comprising:
receiving a receive clock signal of a receive interface included in a receive path between physical layer (PHY) circuitry of the network node and medium access control layer (MAC) circuitry of the network node;
producing multiple sample signals from the receive clock signal using a delay locked loop (DLL) of the receive interface and a local clock signal of the network node;
producing a timestamp offset using the multiple sample signals, wherein the timestamp offset is representative of an offset between local clock signal of the network node and a local clock of a neighbor node of the network node; and
including, by a process of the network node, the timestamp offset in a timestamp of a timing frame to be transmitted by the network node.
