The Time Server will synchronize its time with the Internet Time Servers. Other systems on the network will then synchronize with the company Time Server over the LAN. NTP uses User Datagram Protocol (UDP) on Port 123 to synchronize time. UTC Clocks are referenced by Stratum. Basically, each stratum is a level of accuracy where the top level, or most accurate systems, is numbered as Stratum 0 (Reference Clocks).
The existing Network Time Protocol (NTP) or Simple Network Time Protocol (SNTP) have the advantage of being able to synchronize computers over a local area network but do not have the accuracy required for the most demanding substation applications such as IEC 61850-9-2 Process Bus or IEEE C37.118-2005 Synchrophasors.
