Magpie with Twitter

I’m using Magpie to pull in the RSS from twitter searches and I’m able to get the tweet and the author, but not the time stamp. Does anyone know why this might be? None of the variables available seem to work (http://expressionengine.com/downloads/details/magpie_rss_atom_parser/).

I’m using this in my template:

{exp:magpie url="http://{twitter-rss}" limit="10" refresh="10"}
        {magpie:items}
            <ul>
            <li class="tweet"><a href="http://{link}">{magpie:atom_content}</a></li>
            <li class="tweet-author">via @{magpie:author_name}</li>
                </ul>
        {/magpie:items}
{/exp:magpie}

The feed that I’m putting into the magpie url looks like this search.twitter.com/search.atom?q=”right+on+dynamite”

For some reason, I had to remove the http://www from the weblog entry and hardcode it into the template to get it to work.

Any thoughts on this would be rad. Thanks!
