title: NSDate independent of timezone?
body: <p>I have an app that displays a timetable of certain ferry trips.</p>
  
  <p>If I travel to a different timezone - say 4 hours behind, a 10am ferry trip now shows up as 6am?</p>
  
  <p>I know this has got to do with how dates are treated based on their timezones, but I can't work out how to change that behaviour.</p>
  
  <p>At the moment here's how I am getting the date and displaying it on a UILabel:</p>
  
  <pre><code>NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
  [dateFormatter setDateFormat:@"HH:mm"];
  [self.departureTime setText:[dateFormatter stringFromDate:[self.route objectForKey:@"departureTime"]]];
  [self.arrivalTime setText:[dateFormatter stringFromDate:[self.route objectForKey:@"arrivalTime"]]];
  [dateFormatter release];
  </code></pre>
  
  <p>Thanks in advance for your help.</p>
