title: Java 8 LocalDateTime today at specific hour
body: <p>Is there a nicer/easier way of constructing <code>LocalDateTime</code> object representing today at 6 AM than this?</p>
  
  <pre><code>LocalDateTime todayAt6 = LocalDateTime.now().withHour(6).withMinute(0).withSecond(0).withNano(0);
  </code></pre>
  
  <p>Somehow I don't like dealing with minutes/seconds/nano when all I want to say is <code>now().withHours()</code>.</p>
