The native timestamp type in MySQL is different from datetime type. Internal representation of the timestamp type is UNIX time, This means that timestamp columns are affected by time zone. ``` > SET time_zone = '+00:00'; Query OK, 0 rows affected (0.00 sec) > INSERT INTO time_with_zone(ts,dt) VALUES (NOW(),NOW()); Query OK, 1 row affected (0.02 sec) > SELECT * FROM time_with_zone; +---------------------+---------------------+ | ts | dt | +---------------------+---------------------+ | 2016-02-07 22:11:44 | 2016-02-07 22:11:44 | +---------------------+---------------------+ 1 row in set (0.00 sec) > SET time_zone = '-08:00'; Query OK, 0 rows affected (0.00 sec) > SELECT * FROM time_with_zone; +---------------------+---------------------+ | ts | dt | +---------------------+---------------------+ | 2016-02-07 14:11:44 | 2016-02-07 22:11:44 | +---------------------+---------------------+ 1 row in set (0.00 sec) ```
