title: Java 8: How to create a ZonedDateTime from an Epoch value?
body: <p>Java 8's <code>LocalDateTime</code> has an <code>ofEpochSecond</code> method. Unfortunately, there is no such method in the <code>ZonedDateTime</code>. Now, I have an Epoch value and an explicit <code>ZoneId</code> given. How do I get a <code>ZonedDateTime</code> out of these?</p>
