Yeah, so the qualification in question would be something like "any format that is unabreviated, or in an abbreviated format which can not be misinterpreted as an unabbreviated one".
I think all ambiguities that arrise are cause by time-only specifications where the colon has been omitted. Apart from the one I mentioned, there's "2007" which can mean either the year 2007, or the time 20:07 (without timezone information).
