What is Time Protocol?
{{redlinks|date=April 2020}} {{IPstack}} The '''TIME''' service is an [[Internet Protocol|Internet protocol]] defined in [[RFC:868|RFC 868]]. Its purpose is to provide a site-independent, machine readable date and time. TIME can operate over either [[Transmission Control Protocol|TCP]] or [[User Datagram Protocol|UDP]]. When operating over TCP, a host connects to a server that supports the TIME protocol on TCP port 37. The server then sends the time as a 32-bit unsigned binary number in [[network byte order]] representing a number of seconds since 00:00 (midnight) 1 January, 1900 GMT and closes the connection. The host receives the time and closes the connection. When operating over UDP, the client sends a (usually empty) datagram to UDP port 37. The server responds with a single datagram of length 4 containing the time. There is no connection setup or teardown. ==Related pages== * [[List of well-known ports (computing)|List of well-known ports]] * [[Echo protocol|Echo]] * [[DISCARD]] * [[DAYTIME]] * [[CHARGEN]] * [[Network Time Protocol]] == Other websites == * [[RFC:868|RFC 868]] [[Category:Internet protocols]] [[Category:Application layer protocols]] {{tech-stub}}
