3.1.7  Injection-Date

   The Injection-Date header contains the date and time that the article
   was injected into the network.  Its purpose is to prevent the
   reinjection into the news stream of "stale" articles which have
   already expired by the time they arrive at some relaying or serving
   agent.

   This header is mandatory for new clients, but all agents SHOULD use
   the Date header for this purpose if Injection-Date is not present.

   injection-date  =  "Injection-Date:" SP date-time CRLF


   See the remarks under Section 3.1.3  regarding the syntax of
   date-time and the requirements and recommendations to which it is
   subject.

      NOTE: The date-time in this header would normally be expected to
      be later than the date-time in the Date header, but differences
      between the clocks on the various agents and other special
      circumstances might vitiate that; no provision is made for any
      such discrepancy to be corrected - better that the injecting agent
      should just insert the correct time as it sees it.

   This header is intended to replace the currently-used but
   undocumented "NNTP-Posting-Date" header, whose use is now deprecated.

-   An Injection-Date-header MUST NOT be added to an article except by an
-   injecting agent, hence it will never be present in a proto-article
-   (8.2.1).  It MUST be added by each injecting agent but, once added,
-   it MUST NOT subsequently be changed or removed by any other agent,
-   even during reinjection (8.2.2).

-        Since this header is newly introduced in this standard, other
