      Description

      A confusing warning is printed in the following SQL script:

      mysql> select CAST(TIME('10:20:30') AS DATE) + INTERVAL 1 DAY; show warnings;
      +-------------------------------------------------+
      | CAST(TIME('10:20:30') AS DATE) + INTERVAL 1 DAY |
      +-------------------------------------------------+
      | NULL                                            |
      +-------------------------------------------------+
      1 row in set, 1 warning (0.00 sec)
      
      +---------+------+----------------------------------------------+
      | Level   | Code | Message                                      |
      +---------+------+----------------------------------------------+
      | Warning | 1292 | Truncated incorrect date value: '0000-00-00' |
      +---------+------+----------------------------------------------+
      1 row in set (0.00 sec)
      

      The word "Truncated" is not appropriate here.

      The expected warning is something like:
      "Incorrect datetime value: '0000-00:00 00:00:00'"
      or
      "Incorrect date value: '0000-00:00".

      A warning generated in MySQL-5.1 and 5.5 is also not perfect:
      Incorrect datetime value: '10:20:30'
      But at least does not contain the confusing word "Truncated".
