I don't see where nnrss.el is using the timestamp of an XML file.  Maybe I
missed it.  Did you find it already or are you just saying it *seems* like
it's using the timestamp?

It looks like it's simply using the md5 of the whole article so it's
surprising that it would consider two instances of the item above to be
different.  But again, maybe I've missed something in the code. 

It sounds like you're fetching the feeds outside of nnrss and then nnrss is
reading them.  Is that right?  In my case nnrss is fetching the feeds.
