title: How to convert ZonedDateTime/OffsetDateTime to Date using ThreeTenABP?
body: <p>Using the <a href="https://github.com/JakeWharton/ThreeTenABP" rel="noreferrer">ThreeTen Android Backport</a> library, what is the simplest way to convert a <code>ZonedDateTime</code> or <code>OffsetDateTime</code> into an old-school <code>java.util.Date</code> instance?</p>
  
  <p>If I had full Java 8 libs at my disposal, this of course would be the way to do it (<a href="https://stackoverflow.com/questions/32274369/how-to-convert-zoneddatetime-to-date">as in this question</a>):</p>
  
  <pre><code>Date.from(zonedDateTime.toInstant());
  </code></pre>
  
  <p>But I cannot use that on Android; specifically <a href="https://docs.oracle.com/javase/8/docs/api/java/util/Date.html#from-java.time.Instant-" rel="noreferrer"><code>Date.from(Instant instant)</code></a> is missing.</p>
