1. Set the time zone in Linux. Take CentOS5.5 as an example:

The code is as follows:	Copy code
Cp-f/usr/share/zoneinfo/Asia/Shanghai/etc/localtime

2. Set the time zone in MySQL

Edit the MySQL configuration file: my. cnf/my. ini, and add:

The code is as follows:	Copy code
Default-time-zone = '+ 8:00'

In fact, if the OS time zone of MySQL is set correctly, you do not need to set the time zone in MySQL because the OS time zone is automatically used when the MySQL service is started.

3. Set the time zone in PHP

In the PHP configuration file PHP. ini:

The code is as follows:	Copy code
Date. timezone = "Asia/Shanghai"

After setting, you are advised to restart the system.

If you have purchased a Web space, you are not authorized to configure the time zone in Linux PHP MySQL. In this case, you only need to set the time zone corresponding to the OS in the PHP script, because MySQL uses the OS time zone by default. If the OS time zone is 'Asia/Shanghai', use one of the following two statements:

The code is as follows:	Copy code
Ini_set ('date. timezone ', 'Asia/Shanghai '); Date_default_timezone_set ('Asia/Shanghai ');

2. In windows, we need to set the time zone in PHP. INI.

The code is as follows:	Copy code
Date. timezone = PRC

Set the time zone in the code

The code is as follows:

Copy code

1 date_default_timezone_set ('Asia/Shanghai'); // 'Asia/Shanghai' Asia/Shanghai 2 date_default_timezone_set ('Asia/Chongqing '); // The value of Asia/Chongqing is "Asia/Chongqing" 3 date_default_timezone_set ('prc'); // PRC is "People's Republic of China" 4i ni_set ('date. timezone ', 'etc/GMT-8 '); 5 ini_set ('date. timezone ', 'prc '); 6 ini_set ('date. timezone ', 'Asia/Shanghai '); 7 ini_set ('date. timezone ', 'Asia/Chongqing ');

Any of the above seven methods can meet our needs.

When the system is initialized, add

The code is as follows:	Copy code
Ini_set ('date. timezone ', 'Asia/Shanghai '); Or Date_default_timezone_set ("PRC ");

The time zone difference is 8.
