title: Angular 2 DatePipe shortTime display is off by 6 hours
body: <p>I have a datetime returning as <code>"2016-12-20T19:00:00"</code> and am using a the following pipe on it: <code>{{ dateObj | date:'shortTime' }}</code> I want/expect that to display as 7:00 PM, but it instead is displaying as 1:00 PM. Is this a bug with Angular, or am I doing something wrong?</p>
