Save TimeZone with Date in mongodb
<p>I have java.util.Date field in my document class.</p>

<p>E:g:</p>

<pre><code>@Document(collection = "testdoc")
public class TestDoc {
    @Id
    String id;
    Date startDate;
}
</code></pre>

<p>Even if I set the Date with UTC and IST, it always save in my collection as below,</p>

<pre><code> "startDate" : ISODate("2015-08-21T18:30:00.000Z")
</code></pre>

<p>How can I save the time zone also in mongo collection? What does Z stand in this case?</p>
