mysql str_to_date日期时间值不正确的问题

Question

我无法理解为什么mysql不喜欢我的日期时间值？

mysql> select  STR_TO_DATE('2017-10-06T00:00:00', '%%Y-%%m-%%dT%%H:%%i:%%s');
+---------------------------------------------------------------+
| STR_TO_DATE('2017-10-06T00:00:00', '%%Y-%%m-%%dT%%H:%%i:%%s') |
+---------------------------------------------------------------+
| NULL                                                          |
+---------------------------------------------------------------+
1 row in set, 2 warnings (0.00 sec)

mysql> show warnings
    -> ;
+---------+------+--------------------------------------------------------------------------+
