How to convert ZonedDateTime/OffsetDateTime to Date using ThreeTenABP?

Question

Using the ThreeTen Android Backport library, what is the simplest way to convert a ZonedDateTime or OffsetDateTime into an old-school java.util.Date instance?

If I had full Java 8 libs at my disposal, this of course would be the way to do it (as in this question):

Date.from(zonedDateTime.toInstant());

But I cannot use that on Android; specifically Date.from(Instant instant) is missing.

See DateTimeUtils which handles the methods added to classes like java.util.Date: http://www.threeten.org/threetenbp/apidocs/org/threeten/bp/DateTimeUtils.html

Edit: using that, the complete code would be:

DateTimeUtils.toDate(zonedDateTime.toInstant())
