（已解決）時區出現錯誤訊息

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 /var/www/modules/system/system.admin.inc on line 1735

我調整過了也是一樣，php.ini裡面也都無誤，請前輩幫忙看看還有哪裡可能出錯？
