Mills of the University of … See more In 1979, network time synchronization technology was used in what was possibly the first public demonstration of Internet services running over a trans-Atlantic satellite network, at the National Computer Conference in … See more The 64-bit binary fixed-point timestamps used by NTP consist of a 32-bit part for seconds and a 32-bit part for fractional second, giving a time scale that rolls over every 2 seconds (136 years) and a theoretical resolution of 2 seconds (233 picoseconds). NTP … See more Reference implementation The NTP reference implementation, along with the protocol, has been continuously developed for over 20 years. Backwards compatibility has … See more NTP uses a hierarchical, semi-layered system of time sources. Each level of this hierarchy is termed a stratum and is assigned a number starting with zero for the reference clock at the top. A server synchronized to a stratum n server runs at stratum n + 1. The … See more A typical NTP client regularly polls one or more NTP servers. The client must compute its time offset and round-trip delay.
