有时候在安装zen-cart的时候出现时区错误，提示：
ERROR: date.timezone not set in php.ini. Please contact your hosting company to set the timezone in the server PHP configuration before continuing.
解决办法：
修改php.ini文件，改为：
[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
date.timezone ="Asia/BeiJing"
