PHP 5.3 ทำไม Uncaught ReferenceError: ClearData is not defined ?

login_ok.php:18 Uncaught ReferenceError: ClearData is not defined

วันนี้เจอBug เกี่ยวกับ datetime ของ PHP 5.3 แสดงว่า "login_ok.php:18 Uncaught ReferenceError: ClearData is not defined" ดูที่โค้ดเขียนไว้ว่า 

$date = date("Y-m-d H:i:s");

ให้แก้เป็น

$original_datetime =$date ; '04/01/2013 03:08 PM';
$original_timezone = new DateTimeZone('UTC');

// Instantiate the DateTime object, setting it's date, time and time zone.
$datetime = new DateTime($original_datetime, $original_timezone);

// Set the DateTime object's time zone to convert the time appropriately.
$target_timezone = new DateTimeZone('Asia/Bangkok');
$datetime->setTimeZone($target_timezone);

// Outputs a date/time string based on the time zone you've set on the object.
$triggerOn = $datetime->format('Y-m-d H:i:s');


        $date =$triggerOn;
