I use this workaround:

                 try {
		    if(!empty($modified)) {
			$new_data_time = $content->getAttribute('LAST-MODIFIED');
			if(!empty($new_data_time)) {
			    //Horde::logMessage('SKA: last-modified: '.$new_data_time. "  
".date("Y-m-d H:i:s", $new_data_time), 'NOTICE');
			    //Horde::logMessage('SKA: modified: '.$modified, 'NOTICE');
			    if(is_object($new_data_time) && $new_data_time->before($modified)
			     || !is_object($new_data_time) && date("Y-m-d H:i:s",  
$new_data_time) < $modified) {
				/* LAST-MODIFIED timestamp of existing entry is newer:
				 * don't replace it. */
				//Horde::logMessage('SKA: modified entry is newer skip update', 'NOTICE');
				continue;
			    }
			}
		    }
                 } catch (Horde_Icalendar_Exception $e) {
                 }
