The Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. In operation since before 1985, NTP is one of the oldest Internet protocols in current use. A Stratum 1 Time Server is a network appliance that receives precise time from a hardware reference clock to provide a time resource to client computers. Network Time Protocol (NTP) implements a hierarchical system of time references. The stratum, or hierarchy level, represents the distance of a time server from the source reference clock.Getting Date and Time from NTP Server.
