title: Get [NSDate date] with UTC time
body: <p>I'm developing an iOS 5.0+ app with latest SDK.</p>
  
  <p>I have this code to get a date as string:</p>
  
  <pre><code>NSDateFormatter* formatter = [[NSDateFormatter alloc] init];
  [formatter setDateFormat:@"ddMMyyyy HH:mm"];
  NSDate* now = [NSDate date];
  NSString* dateAsString = [formatter stringFromDate:now];
  </code></pre>
  
  <p>var <code>now</code> is <code>2013-11-20 10:59:21 CET</code> and <code>dateAsString</code> is <code>20112013 10:59</code> but I need to get this date with UTC time. Here in Spain, I think is -1 hour.</p>
  
  <p><strong>How can I get [NSDate date] with UTC time?</strong></p>
