title: MySQL with multiple timestamps
body: <p>Ok, an old hack is no longer working.  Currently using MySQL 5.5.11</p>
  
  <p>In my table I have the below in the same order. </p>
  
  <pre><code>created TIMESTAMP NOT NULL DEFAULT 0000-00-00 00:00:00
  updated TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP
  </code></pre>
  
  <p>On INSERT everything works correctly and NOW() is inserted on both created and updated</p>
  
  <p>Now with MySQL 5.5.11 when I UPDATE, updated works correctly but I loose created (reverts back to 0000-00-00 00:00:00)</p>
  
  <p>How can I overcome this limitation with MySQL's lack of multiple TIMESTAMP support?</p>
