    ah, found this php function which does the trick
    
function create_time_range($start, $end, $by='30 mins') {
	/**
	 * create_time_range 
	 * 
	 * @param mixed $start start time, e.g., 9:30am or 9:30
	 * @param mixed $end   end time, e.g., 5:30 or 17:30
	 * @param string $by   1 hour, 1 mins, 1 secs, etc.
	 * @access public
	 * @return void
	 */
    $start_time = strtotime($start);
    $end_time   = strtotime($end);

    $times = array();
    for ( ;$start_time < $end_time; ) {
        $times[] = $start_time;
        $start_time = strtotime('+'.$by, $start_time);
    }
    $times[] = $start_time;
    return $times;
}
