Also reproducible on MySQL 5.1, 5.5, but not on 5.6, 5.7.

Comment by Alexander Barkov [ 2013-06-13 ]

MySQL-5.6 correctly returns 0:

mysql> SET TIME_ZONE='+02:00'; SELECT VERSION(), UNIX_TIMESTAMP(STR_TO_DATE('2020','%Y'));
Query OK, 0 rows affected (0.00 sec)

---------------------------------------------------+

VERSION() UNIX_TIMESTAMP(STR_TO_DATE('2020','%Y'))

---------------------------------------------------+

5.6.11 0
