The Network Time Protocol (NTP) is widely deployed and used
  in the Internet. However, the standardization status of this
  protocol has lagged in the IETF. RFC 1305 (NTP version 3) was
  published in March 1992 and remains unchanged and at Draft
  Standard status. RFC 1305 represents the majority of full NTP
  implementations deployed today. RFC 2030 (SNTP version 4)
  was published as an Informational RFC in October 1996 as a
  lightweight version of NTP for deployments not requiring the full
  functionality of NTP. SNTP now represents the majority of both
  NTP traffic and NTP implementation issues on the Internet. A
  good deal of work has been produced in the NTP community
  updating both NTPv3 and SNTPv4. This work is ongoing and
  available through the collaborative development effort in the NTP
  community, but it has not been reflected back into the NTP
  The goal of this working group is to document NTPv4 based on
  the extensive work of the NTP community and to advance the
  standardization status of NTP. It is an explicit goal of this effort to
  have NTPv4 interoperate with the deployed base avoiding any
  backwards-incompatible changes.
  A number of topics have been raised as potential work items for
  an update to NTP including support for IPv6, security
  considerations including authentication, automatic configuration
  including possible requirements for DHCP, and algorithm
  improvements. This working group will focus first on delivering
  NTPv4 and will defer additional development efforts until after
  the delivery of NTPv4. Support for IPv6 and defining
  mechanisms for securing NTP transactions is considered part of
  the core NTPv4 functionality. Potential further modifications and
  additions to the NTP protocol will be documented for possible
  further work beyond the initial NTPv4 effort.
  The working group will initially focus on the following
  1. NTPv4 Scope and Requirements Document
  (documenting the scope of the NTPv4 update and
  identifying issues deferred for future work).
  2. NTPv4 Protocol Specification (documenting the protocol
  on the wire)
  3. NTPv4 Architecture and Algorithms Specification
  (documenting the architecture, mathematical algorithms,
  and behavior of NTP servers and clients)
  4. NTPv4 MIB (provision for management and monitoring
  of NTP via SNMP)
