      Description

      This script

      drop table if exists t1;
      create table t1 as  select timestamp('2001-01-01','10:10:10') as a;
      show columns from t1;
      

      creates a VARCHAR(26) column:

      +-------+-------------+------+-----+---------+-------+
      | Field | Type        | Null | Key | Default | Extra |
      +-------+-------------+------+-----+---------+-------+
      | a     | varchar(26) | YES  |     | NULL    |       |
      +-------+-------------+------+-----+---------+-------+
      

      The expected result is a DATETIME column.

      Note: MySQL-5.6 correctly creates a DATETIME column in this scenario.

              This problem should be fixed after MDEV-4724, to avoid a field of type TIME(6)
              being always created, even with a smaller number of fractional digits.
