title: Unexpected output from NSDateFormatter
body: <p>I've been using the following NSDateFormatter code for formatting my date strings with the following output:
  '2013-02-18 03:23:32.928000 +0000'</p>
  
  <p>This has been consistently working until a user with a European iPhone was added where the output changed to: 
  '2013-02-18 02:00:40 AM.118000 +0000'</p>
  
  <pre><code>NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];    
  NSTimeZone *timeZone = [NSTimeZone timeZoneWithName:@"UTC"];    
  [dateFormatter setTimeZone:timeZone];    
  [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss.SSSSSS Z"];
  </code></pre>
  
  <p>Any hint on why the formatter isn't working consistently? </p>
