If memory serves the --iso-8601 option conformed to ISO 8601
a while ago, but the ISO standard changed.  At any rate, the
--iso-8601 option has been deprecated since 2005.  Hmm, I
see that this has not been reflected in the documentation, so
perhaps that's the next step to take for this option, on its
way out the door.

You can get the effect you want, with the command

date +'%Y-%m-%dT%H:%M:%S.%N%:z'
