title: Date is being converted from UTC to BST upon httpclient.put
body: <p>I'm using Angular 12 / Material and a date range picker (mat-date-range-input)</p>
  <p>I have set the following in app.module:</p>
  <pre><code>{
    provide: MAT_MOMENT_DATE_ADAPTER_OPTIONS,
    useValue: {useUtc: true, strict: true}
  }
  </code></pre>
  <p>I'm using a Reactive form to handle the value of the date range picker and I can see (from console logging the form.value) that up until the point of httpclient.put that the date/time are correct</p>
  <p>But the API call, that I pass a PUT body of form.value, the date/time gets transformed to BST</p>
  <p>What would be causing the issue?</p>
