NTP was first defined in the IETF in RFC 958 in 1985. It has been through several iterations in the IETF. The latest, NTPv4 ( RFC 5905) was published in 2010. Today, it is a widely used time synchronization protocol for the synchronization of clocks of various digital systems including computers, networks, and a myriad of devices.Network Time Protocol (NTP) is an internet protocol used to synchronize with computer clock time sources in a network. It belongs to and is one of the oldest parts of the TCP/IP …Instead the most common questions are tried to be answered, enabling everybody to get a working configuration.

David Dalton, Hewlett-Packard.ntpq uses NTP mode 6 packets to communicate with the NTP server, and hence can be used to query any compatible server on the network which permits it. Note that since NTP is a UDP protocol this communication will be somewhat unreliable, especially over large distances in terms of network topology.Users are *strongly* encouraged to upgrade to the network time protocol (NTP), which is both more accurate and more robust. 2. Users of the NIST "DAYTIME" protocol on tcp port 13 are also strongly encouraged to upgrade to the network time protocol, which provides greater accuracy and requires less network bandwidth. The NIST time client (nistime …

The NTP pool is a dynamic collection of networked computers that volunteer to provide highly accurate time via the Network Time Protocol to clients worldwide. The machines that are "in the pool" are part of the pool.ntp.org domain as well as of several subdomains divided by geographical zone and are distributed to NTP clients via round-robin DNS.

Stratum 2 (secondary) servers at the next higher level are synchronized to stratum 1 servers ... Description. The ntpd program is an operating system daemon which sets and maintains the system time of day in synchronism with Internet standard time servers.
