This is intended behaviour: bar checkdate(), which is strict by design, PHP tries 
to be as liberal as possible about accepting dates and conforming invalid values 
to valid ones. This particular behaviour also mimics the long standing way the C 
(and PHP) mktime() works in terms of accepting days outside of the normal range 
for a month.
