title: DatePicker using Time-Interval in SwiftUI
body: <p>I want to use a DatePicker in SwiftUI, it is working fine and as expected. I want to add an Time-interval, like explained: <a href="https://stackoverflow.com/questions/30245341/uidatepicker-15-minute-increments-swift">UIDatePicker 15 Minute Increments Swift</a></p>
  
  <pre><code>DatePicker("Please enter a time", selection: $wakeUp, displayedComponents: .hourAndMinute)
  </code></pre>
  
  <p>Is there a Modifier for that in SwifUI?</p>
