NTP

NTP (Network Time Protocol) is an implementation of the NTP-related RFCs (and proposed RFCs) and provides an openly redistributable reference implementation of the software, including:

• an NTP server (ntpd, and the proposed NTP4 RFC)
• an SNTP client (sntpd, and RFC 2030, and the proposed SNTPv4 Draft RFC)
• tools for verifying, monitoring and configuring the proper operation of the NTP server

The ntpd Server is used on a significant number of computers and routers on the Internet, in orbit around the planet, and even in outer space, providing a robust and stable platform on top of which an organization's timing architecture can be built.

More information on the software, legal issues, security advisories, etc. can be found on the NTP project web site.
