title: Zend_Date language translation
body: <p>I have a function that returns me a date string using <code>Zend_Date</code>.</p>
  
  <pre><code>$date = new Zend_Date();
  $date-&gt;setOptions(array('format_type' =&gt; 'php'));
  $date-&gt;setTimestamp($timestamp);
  return $date-&gt;toString($format);
  </code></pre>
  
  <p>When I set <code>$format</code> to <code>'l, d  F Y'</code> I expect something like:  </p>
  
  <p><code>Środa, 13 stycznia 2010</code> (correct polish string what means <code>Wedneseday, 13 january 2010</code>) and it works good.</p>
  
  <p>But when I open this page in a browser with locale set to english it returns me date string in english instead of polish that I want to see.</p>
  
  <p>What and where should I set to get always polish date regardless of browser settings ?</p>
