 Nope, documentation says clearly:
 `gnus-date-iso8601' (buffer: *scratch*, mode: Lisp Interaction)
 Compiled Lisp function,

   arguments: (date)
   Convert the DATE to YYYYMMDDTHHMMSS. 
By this you imply that an ISO8601 compliant, uhm, entity is not a
valid value for "the DATE".  Hmm...  Maybe the doc-string could be
improved.
