title: How to compare two Carbon Timestamps?
body: <p>I have two timestamps, edited_at which I created and created_at (Laravel's)... 
  In database, both have type timestamp and default value 0000-00-00 00:00:00... But </p>
  
  <p><code>var_dump(edited_at variable)</code> is giving string. While <code>var_dump(created_at variable)</code> is object/Carbon. What is wrong with these timestamps?</p>
  
  <p>I have to compare both after converting into integer using format('U'). I can only call this method on Carbon Object. How can I do that?</p>
