Going by JKR's theory of time travel, the future has already happened. For example, in PoA, before the readers know of the time turner, when things are happening for the "first time", they actually aren't. We don't realise this until later, of course, but things like Harry seeing himself on the other side of the lake, and in the movie, the stone hitting Harry in the back of the head are all things happening in the future.
For present!Harry to go back in time, future!Harry must have already done it for it to be possible, meaning that the future has already happened.
I'm not sure I've explained this very well. It hurts my brain to think about it for too long, really... gah...
