    Description

      set sql_mode=default;
      		 
      drop table if exists t1;
      		 
      create table t1 (a timestamp);
      		 
      insert into t1 values (0);
      		 
      set sql_mode='TRADITIONAL';
      		 
      drop table if exists t2;
      		 
      create table t2 as select * from t1;

      The last statement should fail on error, because zero date is not allowed by sql_mode.

      Note, if I change data time from TIMESTAMP to DATE or DATETIME, it correctly returns the error:

      ERROR 1292 (22007): Incorrect datetime value: '0000-00-00 00:00:00' for column 'a' at row 1
