          Description

          mysql> select to_days('0000-01-01'), date(time('32 00:00:00')),to_days(date(time('32 00:00:00')));

1 row in set, 1 warning (0.00 sec)

1 row in set (0.00 sec)

          The expected result for the third column is 1, without warnings.

          Or the other way around, date(time('32 00:00:00')) should return NULL.
