Showing wrong end time in google calendar

Hi

I import this iCal file in Google calendar. It shows the correct date & Start time but showing the Wrong End Time.
Here is the sample code that i am using & Importing in Google Calendar.

require_once('iCalcreator.class.php' );
$v = new vcalendar(); // create a new calendar instance
$v->setConfig( 'unique_id', 'icaldomain.com' ); // set Your unique id
$v->setProperty( 'method', 'PUBLISH' ); // required of some calendar software
$vevent = new vevent();
$vevent->setProperty( 'dtstart', array( 'year'=>2011, 'month'=>7, 'day'=>1, 'hour'=>19, 'min'=>0, 'sec'=>0 ));
$vevent->setProperty( 'dtend', array( 'year'=>2011, 'month'=>7, 'day'=>1, 'hour'=>22, 'min'=>30, 'sec'=>0 ));
$vevent->setProperty( 'summary', 'Testing the Event in Google Calendar' );
$vevent->setProperty( 'description', 'This is a description For Testing' );
$v->setComponent ( $vevent );
