NTP is … 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. NTP was designed by David L. … Meer weergeven 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 … Meer weergeven A typical NTP client regularly polls one or more NTP servers. The client must compute its time offset and round-trip delay. Time offset θ is positive or negative (client time > server time) difference in absolute time between the two clocks. It is defined by Meer weergeven On the day of a leap second event, ntpd receives notification from either a configuration file, an attached reference clock, or a remote server. Although the NTP clock is … Meer weergeven NTP uses a hierarchical, semi-layered system of time sources.

Web6 mei 2007 · NTP synchronizes timekeeping among a set of distributed time servers and clients. With this synchronization, you can correlate events to the time that system logs were created and the time that other time-specific events occur.
