1. Introduction
Network Time Protocol (NTP) can be used to synchronize the time on network clients, across an IP network, to the
correct time of an NTP time server. TimeTools NTP Servers provide a stratum 1 NTP Time Server for ensuring the time is
correct across an entire network.
The Network Time Server acquires time from the satellite constellation and distributes time across a network using the
TCP/IP Network Time Protocol (NTP).
