A new Request for Comments is now available in the online RFC libraries. RFC 1305: Title: Network Time Protocol (v3) Author: D. Mills Mailbox: mills@udel.edu Pages: 120 Characters: too many to count Obsoletes: RFC 1119 Note: This is a PostScript RFC, a secondary version is available in ASCII. The secondary ASCII version may lack figures and the information encoded in typographic variation (italics, boldface, etc.). Since this information often provides essential context, the ASCII version is at best incomplete and at worst misleading. Anyone expecting to understand this document is strongly encouraged to obtain the PostScript version. SPECIAL NOTICE: The PostScript version is three files. The file made available here is a compressed tar file of those three files. ANY PROBLEMS WITH THIS RFC DISTRIBUTION SHOULD BE REFERRED TO Dave Mills (mills@udel.edu) This document describes the Network Time Protocol (NTP), specifies its formal structure and summarizes information useful for its implementation. NTP provides the mechanisms to synchronize time and coordinate time distribution in a large, diverse internet operating at rates from mundane to lightwave. It uses a returnable-time design in which a distributed subnet of time servers operating in a self- organizing, hierarchical-master-slave configuration synchronizes local clocks within the subnet and to national time standards via wire or radio. The servers can also redistribute reference time via local routing algorithms and time daemons. This is now a Proposed Standard Protocol. This RFC specifies an IAB standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "IAB Official Protocol Standards" for the standardization state and status of this protocol. Distribution of this memo is unlimited.
