title: ZonedDateTime how to set min or max time?
body: <p>How to change time of instatiated ZonedDateTime to f.e.: 'java.time.LocalTime.MIN' or 'java.time.LocalTime.MAX'?</p>
  
  <pre><code>ZonedDateTime date = ZonedDateTime.now();
  </code></pre>
  
  <p>This is good start: <code>ZonedDateTime startDate = date.withHour(0).withMinute(0).withSecond(0).withNano(0);</code></p>
  
  <p>But It will be good to have: 
  <code>ZonedDateTime startDate = date.withTime(LocalTime.Min);
  </code></p>
