title: Date Format of full date response
body: <p>I have this date string:</p>
  
  <blockquote>
    <p>2014-03-09T00:00:00+01:00</p>
  </blockquote>
  
  <p>Tried to parse it to timestamp using this code:</p>
  
  <pre><code>NSDateFormatter * dateFormatter = [[NSDateFormatter alloc] init];
  [dateFormatter setDateFormat:@"yyyy-mm-dd'T'HH:mm:ss"];
  NSDate *date = [dateFormatter dateFromString:response];
  NSLog(@"%@", date);
  NSTimeInterval timestamp = [date timeIntervalSince1970];
  </code></pre>
  
  <p>But it always returns nil in <code>NSLog</code>. What is the proper dateFormat for my date string?</p>
  
  <p>I use same date format in Android app and it works but does not in Obj-C.</p>
