Database time zone issue

Such misunderstandings and JDBC MySQL, resulting in a time stamp is actually stored in the database, and the service system to take the difference between the value of the 13 or 14 hours, this time with the United States is (= 13) No (= 14) daylight saving when closely related.

solve:

mysql> set global time_zone = '+08:00';
Query OK, 0 rows affected (0.00 sec)
 
mysql> set time_zone = '+08:00';
