title: How Can I Set the Default Value of a Timestamp Column to the Current Timestamp with Laravel Migrations?
body: <p>I would like to make a timestamp column with a default value of <code>CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP</code> using the Laravel Schema Builder/Migrations. I have gone through the Laravel documentation several times, and I don't see how I can make that the default for a timestamp column.</p>
  
  <p>The <code>timestamps()</code> function makes the defaults <code>0000-00-00 00:00</code> for both columns that it makes.</p>
