The existing FeedKit code is pretty strict about date formats, so quite possibly you'll be horrified by the very idea of this patch. Nevertheless, I do see quite a few ISO-format dates showing up in RSS feeds.
This patch liberalizes XML date parsing by attempting RFC822, RFC3339, and ISO8601 decoding on every date field rather than limiting each field to its specified format. RFC822 is different enough, and the other two are similar enough, that there should be no difference in the result except that some dates that were previously rejected will now be interpreted correctly.
