我安装WDCP面板后，自行将PHP版本升级到了PHP5.6，然后通过phpinfo输出（），发现提示:
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 the timezone 'UTC' for now, but please set date.timezone to select your timezone.
于是，通过后台面板，更改了php.ini中的设置为：
[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
date.timezone = Asia/Shanghai
