PHP日期函数在Ver 5.3.0中无法正常工作[关闭]

Question

I am using a date function echo date ('Y'); which results in the following error message.

Warning: date() [function.date]: It is not safe to rely on the system's timezone settings.

Is this anything to do with my php.ini page? What change I need to make in php.ini in order to make this code working?

Answer 1

To make that warning go away, you either need to set your timezone with this function:
http://php.net/manual/en/function.date-default-timezone-set.php

or set this in your php.ini:

Update
From the comment below, valid timezones here:
