    Description

      SET sql_mode=''; -- Allow zero date
      		 
      SELECT
      		 
        CAST(TIMESTAMP'0000-00-00 00:00:00.123456' AS DECIMAL(10,6)) AS c1,
      		 
        CAST(TIME'00:00:00.123456' AS DECIMAL(10,6)) AS c2;


      +----------+----------+
      		 
      | c1       | c2       |
      		 
      +----------+----------+
      		 
      | 0.000000 | 0.000000 |
      		 
      +----------+----------+

      The expected result would be 0.123456 for both columns.
