Severus here:

Hermione did use it for homework, that is why she was so exhausted 
all the time, it wasn't just the fact of adding 2 hours to her day, 
it was also the 2 - 3 hours she was adding for homework.  And to 
answer another question, the reason an individual cannot travel back 
in time and change a major event that already took place is. They 
can, but at an extreme cost,  their minds would be bombarded with 
new memories if the event was not kept linear as it was with Harry 
and Hermione.  What I am saying is, could you imagine what would 
happen to your brain if it was re-written to acount for the new 
memories?  Let's us say DD went back 40 years to when LV was TR just 
before the CoS was opened, and DD killed TR and got away with it.  
When he travelled back to the present time, when LV was just 
becoming powerful the first time, there would be no LV and DD's mind 
would be assaulted with 40 years of new memories in an instant.  DD 
would probably be in St. Mungos with severe brain damage.  This is 
just my take on time travel and please feel free to pick it apart.
