[html]

mysql> show variables like '%time_zone%';    

+------------------+--------+ 

| Variable_name    | Value  | 

+------------------+--------+ 

| system_time_zone | CST    | 

| time_zone        | SYSTEM | 

+------------------+--------+ 

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

[html]
set time_zone = timezone
比如北京时间（GMT+0800）
set time_zone = '+8:00'; 如下:
mysql> set time_zone='+8:00';
Query OK, 0 rows affected (0.00 sec)  
 
mysql> show variables like '%time_zone%';
+------------------+--------+
| Variable_name    | Value  |
+------------------+--------+
| system_time_zone | CST    |
| time_zone        | +08:00 |
+------------------+--------+
2 rows in set (0.00 sec)

3 再通过select now()来验证时区

[html]

mysql> show variables like '%time_zone%';    

+------------------+--------+ 

| Variable_name    | Value  | 

+------------------+--------+ 

| system_time_zone | CST    | 

| <span style="color:#3366ff;">time_zone        | +08:00 </span>| 

+------------------+--------+ 

2 rows in set (0.00 sec) 

mysql> select now(); 

+---------------------+ 

| now()               | 

+---------------------+ 

| <span style="color:#3333ff;">2013-08-05 10:35:31 </span>| 

+---------------------+ 

1 row in set (0.00 sec) 

mysql>  <span style="color:#ff0000;">set </span><span style="color:#ff0000;">time_zone='+0:00'; 

</span>Query OK, 0 rows affected (0.00 sec) 

[html]

mysql> show variables like '%time_zone%'; 

+------------------+--------+ 

| Variable_name    | Value  | 

+------------------+--------+ 

| system_time_zone | CST    | 

|<span style="color:#ff0000;"> time_zone        | +00:00 </span>| 

+------------------+--------+ 

2 rows in set (0.00 sec) 

[html]

mysql> select now(); 

+---------------------+ 

| now()               | 

+---------------------+ 

| <span style="color:#ff0000;">2013-08-05 02:35:43 </span>| 

+---------------------+ 

1 row in set (0.00 sec)
