Fixes kohana test_formatted_time test case

public function provider_formatted_time()
	{
		return array(
			// Test the default format
			array('2010-04-16 17:00:00', '5:00PM 16th April 2010'),
			// Now we use our own format
			// Binary date!
			array('01/01/2010 01:00', '1AM 1st January 2010', 'd/m/Y H:i'),
			// Timezones (see #3902)
			array('2011-04-01 01:23:45 Antarctica/South_Pole', '2011-04-01 01:23:45', 'Y-m-d H:i:s e', 'Antarctica/South_Pole'),
