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

问题原因:时区设置不正确造成的
解决方案:
方法1：
（最好的方法）在php.ini里加上找到date.timezone项，设置date.timezone = "Asia/Shanghai"，重启环境就ok了。
方法2：
在需要用到这些时间函数的时候，在页面添加date_default_timezone_set("PRC");
方法3：
在页头加上设置时区ini_set('date.timezone','Asia/Shanghai');
PS:从PHP 5.1.0开始当对使用date()等函数时，如果timezone设置不正确，在每一次调用时间函数时，都会产生E_NOTICE 或者 E_WARNING 信息，而又在php中，date.timezone这个选项，默认情况下是关闭的，无论用什么php命令都是格林威治标准时间，但是PHP5.3中如果没有设置部分时间类函数也会强行抛出了这个错误的。
