Time Turner

I have one problem with the time turner that no one's been able to 
explain to me. How does the time turner know where to "put" H and H 
when they travel back in time? They start in the infimary-- Hermione 
puts the chain around herself and Harry and turns the hourglass three 
times. The next thing they know, they're standing in the entrance 
hall and Hermione drags Harry in the broom closet to hide. If they 
were going back three hours, why didn't they materalize in the same 
place they started-- the hospital ward? Or, if the time turner 
"puts" you in the place that you were at three hours ago, why didn't 
they materialize next to their "other" self? Well, probably the time-
turner is magick-ed so that this problem of meeting yourself doesn't 
happen when you "arrive," so it puts you somewhere away from your 
other self. But how did it know to put H and H in the entrance hall 
three hours before and not, say, Diagon Alley three hours before? 
Any theories?
