警告(2):strtotime()[function.strtotime]:依赖系统的时区设置是不安全的

Question

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/Calcutta' for '5.5/no DST' instead [CORE\cake\libs\cache.php, line 570]
Code | Context

$settings = array(
 "engine" => "File",
 "path" => "C:\xampp\htdocs\cakephp\app\tmp\cache\persistent\",
 "prefix" => "cake_core_",
 "lock" => false,
 "serialize" => true,
 "isWindows" => true,
 "duration" => "+10 seconds",
 "probability" => 100
)

/app/config/core.php:

/**
 * If you are on PHP 5.3 uncomment this line and correct your server timezone
 * to fix the date & time related errors.
 */
    //date_default_timezone_set('UTC');
