Some common date-time methods are easier to manage. From SQL 
query string handling to rendering nicely formatted dates, this helper is 
useful for any Cake application that relies on time elements. 

To include this helper in the application, use this:
var $helpers = array('Time');

Values entered in the place of magic variable slots in the URL are 
passed to the action through the $this->params array. In the previous 
example, the given month would be available in the array as this:
$this->params['month']
and so forth. The $this->params array may be checked or called in the controller and the view.

The available magic functions include the following:
• $Action
• $Day
• $Month
• $Year
• $ID
