title: How to customize Rails localized date format?
body: <p>I am overriding a view from a Rails engine that has this code:</p>
  
  <pre><code>&lt;%= l(item.publish_date, :format =&gt; :long) %&gt;
  </code></pre>
  
  <p>The format of this becomes:</p>
  
  <pre><code>July 17, 2012 23:27
  </code></pre>
  
  <p>I would like to change this so that the date looks more like:</p>
  
  <pre><code>July 17th, 2012  # I don't even really want the time
  </code></pre>
  
  <p>However, I am completely new to how Rails localization works so I don't know how to find the documentation on how to customize this date format. What do I need to do?</p>
