      Description

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a TIME);
      		 
      INSERT INTO t1 VALUES ('10:20:30'),('10:20:30');
      		 
      SELECT MAX(a), MAX(COALESCE(a)) FROM t1;

      returns

      +----------+------------------+
      		 
      | MAX(a)   | MAX(COALESCE(a)) |
      		 
      +----------+------------------+
      		 
      | 10:20:30 | 7594:20:30       |
      		 
      +----------+------------------+

      The expected result is to return 10:20:30 for both columns.
