title: Time zone issue involving date fns format()
body: <pre><code>const dt = new Date('2017-12-12');
  console.log(format(dt, 'YYYY-MM-DD'));
  </code></pre>
  
  <p>The above code logs 2017-12-11 in the US, but 2017-12-12 in India.</p>
  
  <p>I followed this github thread <a href="https://github.com/date-fns/date-fns/issues/489" rel="noreferrer">here</a> and tried out things but am not getting the desired results.</p>
  
  <p>My expectation is to print the same date irrespective of time zone </p>
  
  <p>Why I need this :
  Consider a scenario involving birthdates. If i am giving some input date, it has to be displayed as same date in all regions irrespective of their timezones.</p>
