Given all the clocks in the DoM, time and time-travel appear to be 
one of the phenomenon still under intensive investigation. As far as 
we have been shown so far, the distance that one can travel in time 
is limited. The Time-Turner - which requires one turn for every 
retrograde hour - would be a highly impractical means of traveling 
back more than a few days (just imagine Hermione trying to use her 
Turner to visit 1863!)

Whether there are more powerful versions of the Time-Turner that 
would allow its operator to travel back through years and centuries 
remains to be seen.  However, the fact that so much of early Wizard 
history is but dimly remembered semi-legend - e.g., the founding of 
Hogwarts, and the glaring lacuna in the biographies of Gryffindor, 
Ravenclaw, Hufflepuff and Slytherin - would suggest that either 
wizardly historical researchers are uninterested in time-travel as a 
way of studying history, or that the magical technology to travel back
further in time has yet to be invented.

Still, the fact that time-travel has been used once in the HP 
narrative makes it likely that it will play a role in one of the 
future volumes.
