title: Custom Timestamps in Laravel
body: <p>I want to keep the time record of changes in certain columns of my table. How can I get and save timestamp values in db? I am trying to do it in following way but getting always 0000-00-00 00:00:00 in col_edited_at column.</p>
  
  <pre><code>$case-&gt;col_edited_at = time();
  $case-&gt;save();
  </code></pre>
