title: NSDateFormatter stringFromDate not returning a string
body: <p>I'm trying to change a saved date to mountain standard time using NSDateFormatter but it  doesn't seem to be working.</p>
  
  <p>it's outputting 
  "currentDate: 2013-02-22 23:20:20 +0000 date With date formatter:  other 2000-01-01 07:00:00 +0000" 
  to the console. </p>
  
  <p>It looks like the string isn't being created correctly, but I seem to be calling it in the same way I've seen it called normally.</p>
  
  <p>Suggestions?</p>
  
  <pre><code>    NSTimeZone * mtnTimeZ= [NSTimeZone timeZoneWithAbbreviation:@"MST"];
  
      NSDate *currentDate = [NSDate date];
      NSDateFormatter *dateFormatter = [[NSDateFormatter alloc]init];
      [dateFormatter setTimeZone:mtnTimeZ];
  
      NSString * timeZ = [dateFormatter stringFromDate:currentDate];
  
      NSDate * newDate = [dateFormatter dateFromString:timeZ];
      NSLog(@"currentDate: %@ string With dateFormatter: %@ date made from string %@", currentDate, timeZ, newDate);
  </code></pre>
