The Official NTP documentation is distributed as HTML only and is
available from http://www.eecis.udel.edu/~mills/ntp/html/index.html

Man pages, or other forms of documentation, are maintained by third

The Official NTP documentation is accessible from the "Documentation"
link at http://www.ntp.org/ and http://ntp.isc.org/
