title: date-fns utcToZonedTime has unexpected output
body: <p>According to date-fns docs, utcToZonedTime could be used to get zoned time from utc, but I can't make it to work (and I find it hard to believe they have such a basic bug):</p>
  <pre><code>console.log(dateFnsTz.zonedTimeToUtc(&quot;2021-05-08T02:00:00.000&quot;, &quot;America/Denver&quot;))
  console.log(dateFnsTz.utcToZonedTime(&quot;2021-05-08T08:00:00.000Z&quot;, &quot;America/Denver&quot;))
  </code></pre>
  <p>The [unexpected] output:</p>
  <pre><code>2021-05-08T08:00:00.000Z
  2021-05-08T00:00:00.000Z
  </code></pre>
