title: Input = time, How to allow input of only the hour. No minutes or seconds
body: <p>I want to allow the user to input a time but only allow the input of hours, no minutes or seconds. I understand a text or number field would be better but need to post the input as a time. </p>
  
  <p>I have tried setting the step attribute to 600, however that removes the milliseconds only.</p>
