"In an effort to escape her captors, Hermione Granger attempts to go back in time two hours. However, she ends up in 1977"
that's a little more than 2 hours
but I bookmarked it because it is not Hermione/Snape so it may not be shitty you never know, since how she time traveled there is not important anyway, I'm just nitpicking because it's kinda funny
