Milliseconds to LocalDateTime
<p>How to convert <code>long</code> milliseconds to <code>LocalDateTime</code>?</p>

<p>I have an old code which does some actions with calendar and I want to convert the result milliseconds to LocalDateTime.</p>

<pre><code>final Calendar aMinuteAgo = Calendar.getInstance();
aMinuteAgo.add(Calendar.MINUTE, -1);
//Convert aMinuteAgo.getTimeInMillis() to LocalDateTime
</code></pre>
