title: Extracting universal time/atomic time in flutter
body: <p>I am working on a demo app in a flutter in which I want universal date time. I am using <code>DateTime.now()</code> but it's giving me devise date and time. Is there any way to get standard/universal date time(America) irrespective of device date-time setup. I want that date-time fetched offline without any connectivity with the internet.</p>
