title: How to add a "created at" column in a table
body: <p>I have a form on my website and when somebody fill it the info are copied in my database.</p>
  
  <p>The table is named "form" and its 5 columns:</p>
  
  <ul>
  <li>id</li>
  <li>email </li>
  <li>phone number</li>
  <li>country</li>
  <li>platform</li>
  </ul>
  
  <p>I now need to know when each form entry was submitted, and would like to add a "created at" column which will be filled with the creation time/date timestamp.</p>
  
  <p>Can I retrieve the created date for the row already saved in the table?</p>
