Current events not displaying

We’re using tribe_get_events() function like this :
tribe_get_events( array(
‘posts_per_page’ => $nbAffiche,
‘offset’ => $nbdeb ,
‘start_date’ => date(‘Y-m-d H:i:s’)
) );

This function does not return current events. It returns only future events

The Event Calendar version : 4.9.1

Thanks.
