[phpOpenTracker-User] changing timerange for "Current Activity" report

phpOpenTracker has a great o-o design! Thanks, Sebastian!

That said, how do specify the timerange when I call 
phpOpenTracker_API_visitors_online?

In the index.php example report, I see:
       $resultSet = phpOpenTracker::get(
         array(
           'client_id' => $clientID,
           'api_call'  => 'visitors_online'
         )
       );

The API docs show the method
phpOpenTracker_API_Plugin::_whereTimerange
( $ start,
$ end,
$ table = 'visitors') [inherited]

but I don't know how to put it together. How about an example?

I tried this, but it doesn't work:
       $resultSet = phpOpenTracker::get(
         array(
           'client_id' => $clientID,
           'api_call'  => 'visitors_online',
	 'start'  => (time() - (24*60*60)),
           'end'  => time()
         )
       );

Thanks!
