首先需要查看mysql的当前时区,用time_zone参数

1. mysql> show variables like '%time_zone%';

2. +------------------+--------+

3. | Variable_name | Value |

4. +------------------+--------+

5. | system_time_zone | CST |

6. | time_zone | SYSTEM |

7. +------------------+--------+

8. 2 rows in set (0.00 sec)

1 可以通过修改my.cnf
在 [mysqld] 之下加
default-time-zone=timezone
来修改时区。如：
default-time-zone = '+8:00'
修改完了记得记得重启msyql
注意一定要在 [mysqld] 之下加 ，否则会出现 unknown variable 'default-time-zone=+8:00'

2 另外也可以通过命令行在线修改

1. set time_zone = timezone

2. 比如北京时间（GMT+0800）

3. set time_zone = '+8:00'; 如下:

4. mysql> set time_zone='+8:00';

5. Query OK, 0 rows affected (0.00 sec)

6.  

7. mysql> show variables like '%time_zone%';

8. +------------------+--------+

9. | Variable_name | Value |

10. +------------------+--------+

11. | system_time_zone | CST |

12. | time_zone | +08:00 |

13. +------------------+--------+

14. 2 rows in set (0.00 sec)

15.  

 

3 再通过select now()来验证时区

1. mysql> show variables like '%time_zone%';

2. +------------------+--------+

3. | Variable_name | Value |

4. +------------------+--------+

5. | system_time_zone | CST |

6. | time_zone | +08:00 |

7. +------------------+--------+

8. 2 rows in set (0.00 sec)

9.  

10. mysql> select now();

11. +---------------------+

12. | now() |

13. +---------------------+

14. | 2013-08-05 10:35:31 |

15. +---------------------+

16. 1 row in set (0.00 sec)

17.  

18. mysql> set time_zone='+0:00';

19. Query OK, 0 rows affected (0.00 sec)

1. mysql> show variables like '%time_zone%';

2. +------------------+--------+

3. | Variable_name    | Value  |

4. +------------------+--------+

5. | system_time_zone | CST    |

6. | time_zone        | +00:00 |

7. +------------------+--------+

8. 2 rows in set (0.00 sec)

1. mysql> select now();

2. +---------------------+

3. | now()               |

4. +---------------------+
