Abstract
Aspects of the present disclosure are directed toward apparatuses and methods for time synchronizing between communication nodes of a communications network. In specific embodiments, the apparatus includes nodes having respective clocks circuit and communication circuitry for communicating with other nodes in the network, and the nodes convey or operate on power-related data indicative of power consumption within a power distribution system by communicating the power-related data between communication nodes of the network or system. Each node can provide a time synchronization request to another of the nodes within an interval after being permitted to join into the communications network, and which then results in the node setting the clock circuit to a parameter conveyed from the second node via timing information provided in a uniquely-recognizable data frame as communicated via one of the upper-level layers. The node maintains on-going time synchronization by communicating additional time synchronization requests within predetermined time ranges.
