求高手帮忙--cakephp安装问题！！！

Warning (2): strtotime() [function.strtotime]: 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/Hong_Kong' for 'HKT/8.0/no DST' instead [CORE/cake/libs/cache.php, line 597]


Notice: Trying to get property of non-object in /usr/local/apache/htdocs/php/cake/libs/cache/file.php on line 259

Fatal error: Call to a member function cd() on a non-object in /usr/local/apache/htdocs/php/cake/libs/cache/file.php on line 259


装在LINUX 下面时 的cakephp打开时会出现这样的错误，我已经把TMP的权限改成777了。
