scheduler.getEvent(id).start_date = new Date();
//to update visible event box after it
scheduler.updateEvent(id);

id	string	the event's id
date	Date	the new start date of the event

Example

    start_date: new Date(2013,1,10),
    end_date:   new Date(2013,1,13),
    text:   "Conference"
});
...
scheduler.getEvent(eventId).start_date = new Date(2013,1,09);
scheduler.updateEvent(eventId);
