title: NSTimer doesn't get fired at specified date
body: <p>I'm creating an NSTimer:</p>
  
  <pre><code>    NSTimer *saveProgressSizeTimer = [[NSTimer alloc]
      initWithFireDate:[NSDate dateWithTimeIntervalSinceNow:2.0f]
      interval:1.0f
      target:self
      selector:@selector(myMethod:)
      userInfo:myUserInfo
      repeats:YES];
  </code></pre>
  
  <p>However, the timer doesn't get fired. The method doesn't get invoked.
  If I print my date I get the following:</p>
  
  <blockquote>
    <p>2012-10-12 15:19:02.786 MyApp[1768:303] fire date: 2012-10-12 13:21:02 +0000</p>
  </blockquote>
  
  <p>Shouldn't it be "2012-10-12 15:21:02" ? Somehow the hours are wrong. But why? If I change the Time Zone from UTC/GMT +1 hour (I'm sitting in Germany) to another, the date is still 2012-10-12 13:19:02 plus two seconds.</p>
  
  <p>What am I doing wrong?</p>
  
  <p>Thanks!</p>
