I just fixed a similar bug for MySQL 3.23.12.
In MySQL 3.22.32, it appears to work for me:
mysql> create table t2 (t timestamp default '00000000000000');
Query OK, 0 rows affected (0.00 sec)
mysql> insert into t2 values (0);
Query OK, 1 row affected (0.00 sec)
mysql> select * from t2;
| t |
| 00000000000000 |
1 row in set (0.00 sec)

The DEFAULT value for a timestamp is always NULL (= the current time)
If you don't like this, you should use DATE or DATETIME instead.
