Indeed - it's somewhat IMPOSSIBLE in Muggle World. I'm not so sure 
Wizards keep such records. Few hours, fine.

1) NO MESSING WITH TIME. This is the most important reason why the 
Ministry has strict rules about this. And I see why, as causing a 
mess WOULD create a paradox; there's also the large amount 
of 'unknown' consequences, no matter WHAT you do, so time-travel must 
be limited with this.

2) Court-factor: ability to be in two places at the same time 
discounts using alibi as proof of innosence.

3) IF one could go back in time for centuries, and then return, it 
would be of great help to historians! which leads me to wonder if 
boring Binns ever used a TimeTurner to get experience of History, and 
then he became a ghost because he didn't make it back on time!
