1. A method for initializing a self-synchronizing coherent network Primary Reference Time Clock (cnPRTC) mesh, comprising:
initializing a self-synchronizing cnPRTC mesh during a start-up period; and
setting, by a Universal Time Coordinated (UTC(k)) node connected to a selected cnPRTC node of the self-synchronizing cnPRTC mesh, the selected cnPRTC node to a UTC(k) time provided by the UTC(k) node during the start-up period based on a Global Navigation Satellite System (GNSS) system failing to provide the selected cnPRTC node with a GNSS time during the start-up period;
wherein setting the selected cnPRTC node comprises directly inserting the UTC(k) time into a clock combiner of the selected cnPRTC node such that the inserted UTC(k) time replaces weighted times provided to the selected cnPRTC node by local time sources and remote time sources.
