What is ambiguous about that (deliberate) example?  The ISO 8601 standard 
is an international standard, and the meaning of "2001-02-03" is defined 
there.  There is even a reference to the standard on the help page, and 
the `default formats' are specified under `Arguments'.

The point was that people should not guess at the meaning, but follow up 
the pointers given.
