下面是访问cakephp目录下的index.php浏览器给出的提示：
- PHP code
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 'UTC' for '8.0/no DST' instead [CORE\cake\libs\cache.php, line 597]Code | Context$settings = array(
