PHP Warning: phpinfo(): It is not safe to rely on the system\'s timezone settings

[Sat Oct 12 09:14:53 2010] [error] [client 192.168.1.162] PHP Warning:  phpinfo(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting 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 selected 'Asia/Chongqing' for 'CST/8.0/no DST' instead in /www/index.php on line 2

解决方法是

[root@localhost lib]# vi /usr/local/lib/php.ini

[Date]

; Defines the default timezone used by the date functions

; http://php.net/date.timezone

date.timezone =Asia/Shanghai
