   The Network Time Protocol version 4 (NTPv4), as defined in RFC 5905,
   is the mechanism used by NTP clients to synchronize with NTP servers
   across the Internet.  This document specifies an extension to the
   NTPv4 client, named Chronos, which is used as a "watchdog" alongside
   NTPv4, and provides improved security against time shifting attacks.
   Chronos involves changes to the NTP client's system process only and
   is backwards compatible with NTPv4 servers.
