dc:date parsing?

Not sure if you're going to be interested in this, but I found that dc:date wasnt getting parsed correctly for this feed: http://www.tabletitans.com/feed, and this patch fixes that.  I wrote the oneliner in coffeescript, which is why its rather ugly.

date = utils.get(el) ? new Date(el[0]?['#']) ? new Date(el['#']) ? null

but it should be backwards compatible.
