title: How do I get the commit date and the merge date when looking at the commit history of a file in Github?
body: <p>i.e. on <a href="https://github.com/rails/rails/commits/3-2-stable/activerecord/lib/active_record/fixtures.rb" rel="nofollow">this page</a></p>
  
  <p>Do the dates refer to when the commit was made? or when it was merged in? And how can I find out the other?</p>
  
  <p>Thank you,</p>
  
  <p>edit: Ideally I don't have to clone the repo down and use the git CLI.</p>
  
  <p>edit2: It looks like the dates in that link are the dates from when the commit was made. So how does one find out when the commit was merged into the branch using Github's GUI?</p>
