title: Git Folder Difference between between two times for a single branch in TFS
body: <p>I am newbie to git and TFS and I wanted to get difference between the files that have changed from time t1 to t2 committed for a single branch. I have tried using git diff master master@{yyyy-mm-dd} format but this does not seem to be working for me. Is there any other method by which I can get this difference.
  I wanted to compare what has been changed on the repository between two time frames.</p>
