PHP Warning: date(): 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 gett ing this warning,you most likely misspelled the timezone identifier. We selected 'Asia/Chongqing' for 'CST/8.0/no DST' instead in /data0/htdocs/www.qttc.net/function/function.PHP on line 542

这种方法有个缺点，就是所有的页面都得添加

第二种

在PHP.ini里找到date.timezone这行，把值改成PRC，如date.timezone = PRC。如果没有这一行直接加上就好。最后重启WEB服务器与PHP即可。
