Ok, so basically there's a lot left to work out for your parser.
In that case, I think the ideal thing to do would be to release Joshua's
parser now as DT::F::ISO8601, and then to continue work on yours, making
it backwards compatible with Joshua's.
Or in other words, please merge the damn things! ;)
