title: Determine when a ScheduledExecutorService will fire next
body: <p>Is there a way to determine the current millisecond or other time measure of when a ScheduledExecutorService is going to fire next?</p>
  
  <pre><code>scheduleTaskExecutorUpdate = Executors.newSingleThreadScheduledExecutor();
  </code></pre>
  
  <p>I have a longer running <code>ScheduledExecutorService(A)</code> and from a shorter running <code>ScheduledExecutorService(B)</code> I would like to update a TextView, display a countdown of when <code>ScheduledExecutorService(A)</code> is going to fire next.</p>
