5.1.  Date

   The Date-header contains the date and time that the article was
   prepared by the poster ready for transmission and SHOULD express the
   poster's local time. The content syntax makes use of syntax defined
   in [RFC 2822], subject to the following revised definition of zone.

      header              =/ Date-header
      Date-header         = "Date" ":" SP Date-content
      Date-content        = date-time
      zone                = (( "+" / "-" ) 4DIGIT) / "UT" / "GMT"

   The forms "UT" and "GMT" (indicating universal time) are to be
   regarded as obsolete synonyms for "+0000". They MUST be accepted, and
   passed on unchanged, by all agents, but they MUST NOT be generated as
   part of new articles by posting and injecting agents.  The date-time
   MUST be semantically valid as required by [RFC 2822].  Although
   folding white space is permitted throughout the date-time syntax, it
   is RECOMMENDED that a single space be used in each place that FWS
   appears (whether it is required or optional).

        NOTE: A convention that is sometimes followed is to add a
        comment, after the date-time, containing the time zone in
        human-readable form, but many of the abbreviations commonly used
        for this purpose are ambiguous. The value given by the <zone> is
        the only definitive form.

   In order to prevent the reinjection of expired articles into the news
   stream, relaying and serving agents MUST refuse "stale" articles
   whose Date-header predates the earliest articles of which they
   normally keep record, or which is more than 24 hours into the future
   (though they MAY use a margin less than that 24 hours). Relaying
   agents MUST NOT modify the Date-header in transit.
