 If the author and commit date are different, you can manually change the commit date in the URL to see the commit details.
 
 For example:
-- This URL uses the author date of `2016-07-13`:
+- This URL uses the author date of `2018-04-03`:
 
-  `https://github.com/your-organization-or-personal-account/your-repository/commits?author=octocat&since=2016-07-13T00:00:00Z&until=2016-07-13T23:59:59Z`
-- This URL uses the commit date of `2016-07-19`:
+  `https://github.com/your-organization-or-personal-account/your-repository/commits?author=octocat&since=2018-04-03T00:00:00Z&until=2018-04-03T23:59:59Z`
+- This URL uses the commit date of `2018-04-10`:
 
-  `https://github.com/your-organization-or-personal-account/your-repository/commits?author=octocat&since=2016-07-19T00:00:00Z&until=2016-07-19T23:59:59Z`
