    Description

      Setup:

      CREATE TABLE t1 (c1 TIME);
      		 
      INSERT INTO t1 VALUES('06:01:00');

      Now:

      SELECT UNIX_TIMESTAMP(CONCAT('2018-01-01 ',c1)) FROM t1;

      produces "1514815560.000000"
      while:

      SELECT UNIX_TIMESTAMP(CAST(CONCAT('2018-01-01 ',c1) AS DATETIME)) FROM t1;

      produces "1514815560"

      Yet:

      SELECT UNIX_TIMESTAMP(CONCAT('2018-01-01 ','06:01:00'));

      produces "1514815260"
      and

      SELECT UNIX_TIMESTAMP(CONCAT('2018-01-01 ',CAST('06:01:00' AS time)));

      still produces "1514815260"

      Same as MySQL bug #82070. Similar to MDEV-3922.

      Also, per https://mariadb.com/kb/en/library/unix_timestamp/

      SELECT UNIX_TIMESTAMP('2007-11-30 10:30:19');

      should return decimal as of 5.3, but it does not in 5.5.
