While this is not the easiest way, you can specify which date you want to go to by adding the following parameter to the Time Manager URL:
CalendarDate=MM%2FDD%2FYYYY
where you will replace MM = Month, DD = Day, YYYY = Year
So let's say you want to jump to September, you would have this as your Time Manager app URL:
http://<domain>.officelive.com/TimeManager/Lists/Schedule and Reservations/calendar.aspx?CalendarDate=9%2F1%2F2008
Hope this helps!
