I would reject articles with Date headers that cannot be parsed.  I don't
see any good reason to accept those any more than we do already (we're
already lax about what we accept).

The purpose of requiring relaying agents to look at Injection-Date instead
of Date was primarily to handle dates in the past, not dates in the
future, but I don't think it will cause harm there either.  Such articles
will be rejected by peers that don't understand Injection-Date, but that's
why nnrpd rejects such articles so that we don't introduce bad articles.
