date(): It is not safe to rely on the system’s timezone settings.

在执行php脚本时出现的错误：

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 getting this warning, you most likely misspelled the timezone identifier. We selected ‘Asia/Chongqing’ for ‘CST/8.0/no DST’ instead

解决方法：

在php.in 配置文件里添加：date.timezone = "Asia/Shanghai"
