   The Network Time Protocol version 4 (NTPv4) defines the peer process,
   the clock filter algorithm, the system process and the clock
   description algorithm.  The clock filter algorithm and the system
   process, as defined in RFC 5905, are the mechanism according to which
   an NTP client chooses the NTP servers it synchronized with.  This
   document specifies an alternative set of client mechanisms, named
   Chronos, that is backward compatible with NTPv4, and offers an
   improved level of security against time shifting attacks.
