          Description

          In 5.1-micro, the following expression

          cast(timestamp(f1) AS time)

          returns NULL if f1 = 0000-00-00 00:00:00 . In mysql-5.1 , it returns 00:00:00, which is the more intuitive result

          test case:

          drop table t1;
          create table t1 (f1 datetime);
          insert into t1 values ('0000-00-00 00:00:00');
          select cast(timestamp(f1) AS time) from t1;
