 2002-01-01   <-- It should be 2002-01-12

 2002-12-02


For some reason it's getting caught up on January.  I know these dates are
Unambiguous however I think there might be a bug there.

It would be my first bug ;)

I think you need FM:

regression=# select to_date('January 12 2002','FMMonth dd yyyy');
  to_date
------------
 2002-01-12
(1 row)

Without that, the to_date scanner assumes it should be dealing with
fixed-width fields.  I think this is moderately broken myself, but
maybe that's the way Oracle does it...
