[Cake] Choosing a tin to work on

I agree with xnoreq. The algorithm as it is will not always return the least overdue tin. It returns either the lowest positive tdiff (if all tdiff values are positive), or the lowest negative one (if not all tdiff values are positive). This could be accomplished just with "if (tdiff<=best_time)" as xnoreq pointed out.
