Looking for time elapsed for Grand Slams

[3zz]

Hi guys, I'm working on a paper on the equality of pay in Grand Slam tennis between men and women. One variable that I would like to include is the amount of time the winner of a Grand Slam needed to complete his/her victory. Can anyone tell me where I can find these historical stats?

So this is about time elapsed in the 7 matches to win the Grand Slam tour.

Thanks a lot!
