title: Incorrent day format moment.js
body: <p>I have an input with the following date inside my util function (the first argument) - '2013-12-15'. I use the format 'MM/DD/YYYY' as a second argument for the format moment.js method. Actual result: 12/14/2013 instead of 12/15/2013 (input date equals to '2013-12-15'). The question is - why moment subtract one day after formatting?</p>
  
  <pre><code>export const formatDateTime = (date, format = MM/DD/YYYY) =&gt; {
      let useFormat = format
  
      return moment
          .utc(date)
          .tz('America/New_York')
          .format(useFormat)
  } // return '12/14/2013'
  
  </code></pre>
