Actually, as I said a few days ago, I absolutely adore JKR's version of 
time travelling, because she makes that an impossibility. In a nutshell, 
"you can't change what has already happened".

Buckbeak wasn't executed, Harry saw himself (his future self) cast the 
Patronus.

If the Potters hadn't been attacked, nobody would've known to go back to 
save them. The Potters *were* attacked and very quickly killed - there's no 
way to change that fact. Therefore there is no point in going back to save 
them, because it's already known that they were dead.
