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] (but see the revised definition of zone in section
   2.4.2).

      header              =/ Date-header
      Date-header         = "Date" ":" SP Date-content
      Date-content        = date-time

   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).

   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.
