ISO 8601 uses dashes, not slashes, to separate yyyy-mm-dd.  Please
add support for "2007-12", and I'd mildly prefer to see "2007/12" be
a syntax error (to encourage people to use the ISO 8601 style).  See
<http://www.cl.cam.ac.uk/~mgk25/iso-time.html> for a reasonable summary
of the ISO 8601 date/time format.

Yes, please.
