I was thinking that since INN's definition of ``valid date'' is more generous than the RFCs', INN doesn't reject all nonconforming dates. E.g. from looking at inn/lib/parsedate.y, it appears that INN accepts and retransmits nonsense like Date: 1:2:3pm Serendipitous Tuesday, 13 Nov. 092 under the impression that it's equivalent to Date: Friday, 13 Nov 1992 13:02:03 GMT Propagating such nonsense causes problems for folks like Lyons who have stricter date parsers. If you're going to accept nonsense, you must rewrite it before retransmitting it; if you don't believe in rewriting headers, you mustn't retransmit articles with nonconforming headers. Unfortunately, neither C News nor INN conforms to the RFCs on this point, at least not yet.
