title: How to format a date to always show as UTC
body: <p>I am trying to format a date such that it always shows as UTC e.g. in the format 'dd/mm/YYYY HH:MM UTC'. So far I have this code:</p>
  <pre><code>const options = {
      year: 'numeric',
      month: 'numeric',
      day: 'numeric',
      hour: 'numeric',
      minute: 'numeric',
      timezone: 'UTC',
      timeZoneName: 'short'
  };
  
  const formattedTime = new Intl.DateTimeFormat('en-GB', options).format(new Date(unixTimestamp))
  </code></pre>
  <p>However this gives me a time in either GMT or BST, e.g.</p>
  <pre><code>24/11/2021, 05:51 GMT
  27/10/2021, 05:09 BST
  </code></pre>
  <p>What I would like is for the time to be always shown as UTC so in the case of the above examples:</p>
  <pre><code>24/11/2021, 05:51 UTC
  27/10/2021, 04:09 UTC
  </code></pre>
  <p>Is there a way to configure DateTimeFormat to do this or should I be using something else? I'd rather not resort to importing a library if at all possible.</p>
