title: rfc850 date format and NSDateFormatter
body: <p>Im having a hard tim getting the NSDateFormatter to give me a correct date format.  I need it to look like this:</p>
  
  <pre><code>Mon, 04 Jan 2010 10:10:00 GMT
  </code></pre>
  
  <p>But I am getting:</p>
  
  <pre><code>Mon, 04 Jan 2010 10:10:00 GMT+00:00
  </code></pre>
  
  <p>Using the format string:</p>
  
  <pre><code>EEE',' dd' 'MMM' 'yyyy HH':'mm':'ss z
  </code></pre>
  
  <p>No matter what value for timezone I use, the +00:00 appears to be stuck on the end.  I realize I could just remove it form the resulting string, but that feels like cheating.</p>
  
  <p>So how do I get the date formatter to not include a time offset value?</p>
