title: Change datetime of a Git commit
body: <p>Is it possible to change the date of a commit in Git?</p>
  
  <p>If yes does this modification leave any track?</p>
  
  <p>Basically I want to change the date of a commit but it should not be visible to anyone that the date has changed by me.</p>
  
  <p>As I have researched it is possible to change the date by using <code>git filter-branch</code> but I do not know whether this leaves any history. </p>
