Apply timezone to Date object
<pre><code>    Date now = new Date();
    Date then = new Date((long)obj.timestamp*1000);

    TimeZone tz = TimeZone.getDefault();
</code></pre>

<p>Not very familiar with java, but is there any way to apply a timezone to a <code>Date</code> object? I found <a href="http://stackoverflow.com/questions/230126/how-to-handle-calendar-timezones-using-java">this</a> thread, but this is about Calendar timezones, which i believe is something different?</p>
