title: PHP mysql auto insert timestamp
body: <p>Say I have a table name auto_parts with these fields.
  <code>id, part, price, timestamp</code>
  and I insert a new row via php as so:</p>
  
  <pre><code>$query = "insert into auto_parts(id, part, price, timestamp)
    values(1, 'axle', 200)"
  mysql_query($query);
  </code></pre>
  
  <p>will that automatically add the timestamp.
  Or do I have to insert a value for timestamp myself?</p>
