title: Passing date as search parameter issue
body: <p>When a user searches post by date, I need to pass the date as a search parameter through the url.</p>
  
  <p>Like : <a href="http://siteurl/post/index/created:03/15/2012" rel="nofollow">http://siteurl/post/index/created:03/15/2012</a></p>
  
  <p>As you can see the date format is <code>mm/dd/yy</code> which is creating an issue, as a result I'm getting only <code>03</code> as a value in the request.</p>
  
  <p><strong>Edited</strong> : Some code from my params i get in controller.</p>
  
  <pre><code>Array
  (
  
  [controller] =&gt; posts
  
  [action] =&gt; index
  
  [named] =&gt; Array
      (
          [created] =&gt; 03
      )
  
  [pass] =&gt; Array
      (
          [0] =&gt; 15
          [1] =&gt; 2012
      )
  
  [plugin] =&gt; 
  [form] =&gt; Array
      (
      )
  
  [url] =&gt; Array
      (
          [url] =&gt; /posts/index/created:03/15/2012
      )
  
  [isAjax] =&gt; 
  )
  </code></pre>
  
  <p>Is there a way that a user can select date in <code>mm/dd/yy</code> format and then I can change to another format after submitting the form?</p>
