Problems of ensuring the reliability of the time scale formed by the master clock

Today, time synchronization systems that form and transmit time scales with accuracy within tens of ns are becoming increasingly relevant. The basis of such systems are complexes of devices that implement the functions of the master clock. Because since the time scale is not a physical quantity, then in any implementation of this clock, a channel for obtaining data on the UTC time scale is required. Due to various interferences and disturbances in this communication channel, the reliability of the reception of the UTC reference time scale can be violated, which leads to serious errors in the synchronization system and disruptions in the operation of communication networks. This article discusses some mechanisms for ensuring the reliability of data on the time scale formed by the master clocks of time synchronization systems.
