title: Zend date is singleton?
body: <p>I have the following code:</p>
  
  <pre><code>$fromDate = new Zend_Date();
  $this-&gt;view-&gt;fromDate = $fromDate-&gt;getIso();
  $this-&gt;mongoFromDate = new MongoDate($fromDate-&gt;getTimeStamp());
  
  $toDate = new Zend_Date();
  $toDate-&gt;setDay(3);
  $this-&gt;view-&gt;toDate = $toDate-&gt;getIso();
  $this-&gt;mongoToDate = new MongoDate($toDate-&gt;getTimeStamp());
  </code></pre>
  
  <p>Which for some reason is setting the $this->view->toDate and $this->view->fromDate values to the same value. Any thoughts on what could cause this? I'm completely stumped.</p>
  
  <p>Thanks!</p>
