      Description

      This SQL query returns a wrong result:

      mysql> SELECT CONVERT_TZ(TIME('00:00:00'),'+00:00','+7:5'); show warnings;
      +----------------------------------------------+
      | CONVERT_TZ(TIME('00:00:00'),'+00:00','+7:5') |
      +----------------------------------------------+
      | 0000-00-00 00:00:00                          |
      +----------------------------------------------+
      1 row in set (0.00 sec)
      

      The expected result is NULL with a warning.
      The same problem happens in this query:

      mysql> SELECT CONVERT_TZ(TIME('2010-01-01 00:00:00'),'+00:00','+7:5');
      +---------------------------------------------------------+
      | CONVERT_TZ(TIME('2010-01-01 00:00:00'),'+00:00','+7:5') |
      +---------------------------------------------------------+
      | 0000-00-00 00:00:00                                     |
      +---------------------------------------------------------+
      1 row in set (0.00 sec)
      

      Note: this problem is not repeatable with mysql-5.1, 5.5.
