title: LocalDateTime.now() has different levels of precision on Windows and Mac machine
body: <p>When creating a new <code>LocalDateTime</code> using <code>LocalDateTime.now()</code> on my Mac and Windows machine i get a nano <strong>precision of 6</strong> on my Mac and a nano <strong>precision of 3</strong> on my Windows machine. Both are running <code>jdk-1.8.0-172</code>. </p>
  
  <ul>
  <li>Is it possible to limit or increase the precision on one of the
  machines?</li>
  <li>And why is the precision actually different?</li>
  </ul>
