   Unless I'm mistaken, most NNTP reader connections won't accept   
   a POST Date: header too far from the current time.   
      
   (I haven't been a news admin for going on 20 years, so my memory   
   may be faulty.)   
      
   And, an anecdote:  I used to graph article transit time by comparing   
   the article Date: to the arrival time, and discovered that most people's   
   software was accurate enough to determine if a feed was slow.  That   
   was in the 00's though, so maybe things are different now.   
      
   Anyway, it was fairly easy, since that info is in the history   
   file.
