<p>This protocol was designed in a way that makes migration from <cite>XEP-0090</cite> straightforward. This document specifies a different format for the XML character data of the &lt;utc&gt; element (compliant with <cite>XEP-0082</cite>) and specifies a new &lt;tzo&gt; element for the numeric offset from UTC, while removing the formerly optional and effectively useless &lt;display/&gt; and &lt;tz/&gt; elements.</p>
<p>Implementations that support <cite>XEP-0090</cite> should support the protocol defined herein as soon as possible, but should continue to support the protocol defined in <cite>XEP-0090</cite> for backwards compatibility until the status of that specification is changed to Obsolete.</p>
