          Description

          For the query:

          SELECT CAST(010203101112 AS DATETIME(1)) AS c1,CAST(010203101112.3+0e0 AS DATETIME(1)) AS c2,CAST(010203101112.3+0e0 AS DATETIME(1)) AS c3;

          MySQL5.6 consistently returns values with YEAR=2001:

          +-----------------------+-----------------------+-----------------------+
| c1                    | c2                    | c3                    |
+-----------------------+-----------------------+-----------------------+
| 2001-02-03 10:11:12.0 | 2001-02-03 10:11:12.3 | 2001-02-03 10:11:12.3 |
+-----------------------+-----------------------+-----------------------+

          MariaDB returns either 2001 or 0001 in year:

          +-----------------------+-----------------------+-----------------------+
| c1                    | c2                    | c3                    |
+-----------------------+-----------------------+-----------------------+
| 2001-02-03 10:11:12.0 | 0001-02-03 10:11:12.2 | 0001-02-03 10:11:12.2 |
+-----------------------+-----------------------+-----------------------+

          MySQL-5.6 results look better.
