So long as we're talking about time travel...

Something else that has always bothered me...

When Harry and Hermione go back in time, they are standing in the 
hospital wing. Dumbledore has just locked them in.

When Hermione turns the hourglass three times, they end up in the 
Entrance Hall.

Now, JKR can create whatever rules she wants for her world, so long 
as she's consistent within that world. She doesn't have to follow any 
other established time travel fiction rules.

BUT... many of the classic Time Travel stories, such as the Time 
Machine and Back to the Future, use the "change time, not place" 
theory.

Under that theory, you go back in time, but you don't move. If they 
could somehow turn the Time Turner back 1,000,000 times, they would 
go back 1,000,000 hours, or about 114 years, but they would be in the 
hospital wing of Hogwarts, 114 years back.
