Inserting a huge time value into a datetime column produces a wrong result.

          Description

          mysql> create table t1 (a datetime);
Query OK, 0 rows affected (0.07 sec)

mysql> insert into t1 values (time('800:20:30'));
Query OK, 1 row affected (0.03 sec)

mysql> select * from t1;
+---------------------+
| a                   |
+---------------------+
| 0000-00-08 00:20:30 |
+---------------------+
1 row in set (0.00 sec)

          The above result looks wrong.

          Explicit conversion from time to datetime seems to return a much better result:

          mysql> select cast(time('800:20:30') as datetime);
+-------------------------------------+
| cast(time('800:20:30') as datetime) |
+-------------------------------------+
| 0000-01-02 08:20:30                 |
+-------------------------------------+
1 row in set (0.00 sec)
