    Description

      SET @@timestamp=UNIX_TIMESTAMP('2001-01-01 10:20:30');
      		 
      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a TIMESTAMP,b TIMESTAMP);
      		 
      INSERT INTO t1 VALUES ('2001-01-01 00:00:00','2001-01-01 23:59:59');
      		 
      SELECT * FROM t1 WHERE TIME'10:20:30' BETWEEN a and b;

      erroneously returns empty set.

      If I change one of the columns from TIMESTAMP to DATETIME it correctly returns one row:

      SET @@timestamp=UNIX_TIMESTAMP('2001-01-01 10:20:30');
      		 
      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a TIMESTAMP,b DATETIME);
      		 
      INSERT INTO t1 VALUES ('2001-01-01 00:00:00','2001-01-01 23:59:59');
      		 
      SELECT * FROM t1 WHERE TIME'10:20:30' BETWEEN a and b;
