登录OSB管理页面时报date_default_timezone_set()解决方法

登录OSB管理页面时报时区错误如下：

Warning: date() [function.date]: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We had to select 'UTC' because your platform doesn't provide functionality for the guessing algorithm in /apps/oracle/OSBackup/apache/htdocs/php/common.php on line 1963

Cause:
这是因为PHP所取的时间是格林威治标准时间，所以和你当地的时间会有出入格林威治标准时间和北京时间大概差8个小时左右，我们可以按照下面的方法解决。

解决办法：

1、在页头使用date_default_timezone_set()设置我的默认时区为北京时间，即

<?php

date_default_timezone_set("PRC");

?>就可以了。

2、在php.ini中设置date.timezone的值为PRC，设置好以后的为：date.timezone=PRC，同时取消这一行代码的注释，即去掉前面的分号就可以了。

 

打开php5.ini查找date.timezone 去掉前面的分号　= 后面加XXX，重启http服务（如apache2或iis等）即可。

XXX可以任意正确的值。对于我们国内来 说：可以为以下值：Asia/Chongqing ，Asia/Shanghai ，Asia/Urumqi （依次为重庆，上海，乌鲁木齐）港台地区可用：Asia/Macao ，Asia/Hong_Kong ，Asia/Taipei （依次为澳门，香港，台北），还有新加坡：Asia/Singapore，当然PRC也行。
