Internet-Draft     IANA Timezone Database YANG Module          June 2012


1.  Introduction

   This document defines the initial version of the iana-timezones YANG
   module for timezone configuration.

   The iana-timezones module reflects IANA's existing "timezone
   database".  The latest revision of the module can be obtained from
   the IANA web site.

   Whenever a new timezone name is added to the IANA "timezone
   database", the iana-timezones module is updated by IANA.

3.  IANA Considerations

   This document defines the initial version of the IANA-maintained
   iana-timezones YANG module.

   The iana-timezones module is intended to reflect the IANA "timezone
   database".  When a timezone location is added to the database, the

Internet-Draft     IANA Timezone Database YANG Module          June 2012


   "iana-timezone" enumeration MUST be updated as defined in RFC 6020
   Section 10 to add the newly created timezone location to the
   enumeration.  The new "enum" statement MUST be added to the "iana-
   timezone" typedef with the same name as the newly added timezone
   location.  A new enum value MUST be allocated by IANA and applied to
   the newly created enum entry.  New entries MAY be placed in any order
   in the enumeration as long as the previously assigned enumeration
   values are not changed.

   When the iana-timezones YANG module is updated, a new "revision"
   statement must be added.

   This document registers one URI in the IETF XML registry [RFC3688].
   Following the format in RFC 3688, the following registration is
   requested to be made.

      URI: urn:ietf:params:xml:ns:yang:iana-timezones

      Registrant Contact: IANA.

      XML: N/A, the requested URI is an XML namespace.

   This document registers one YANG module in the YANG Module Names
   registry [RFC6020].

      name: iana-timezones

      namespace: urn:ietf:params:xml:ns:yang:iana-timezones

4.  Security Considerations

   Since this document does not introduce any technology or protocol,
   there are no security issues to be considered for this document
   itself.
