Abstract

A method of synchronizing a local estimation of global network time (LNT) of a receiving node (70, 76, 80, 84, 90, and 94) on a network to a global network time reference (GNT) is provided. The free running nodes (70, 76, 80, 84, 90, and 94) receive precise time protocol synchronization messages and determine a ratio (R) and an offset (TO) based on time data extracted from the messages.
