Codezwiz >> Forums >> General PHP Nuke Help >> Rss feed help needed

Hope all is well. I've got myself into a pickle and not quite sure what to do about it. It may be simple enough...I'm just not getting it.

I'm using the following code to generate my forums rss feed which works fine btw for twitter using twitterfeed. The problem I'm having is with Facebook RSS Graffiti not finding a pub date in each of my feeds. I need to add this but I will admit...I'm clueless how to add the "pubdate" element to this code.

<?php

include("mainfile.php");
global $prefix, $dbi, $sitename, $user, $cookie, $group_id;
header("Content-Type: text/xml");
echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>";
echo "<rss version=\"0.91\">";
echo "<channel>";
echo "<title>".htmlspecialchars($sitename)."</title>\n";
echo "<link>$nukeurl</link>\n";
echo "<description>".htmlspecialchars($backend_title)."</description>\n";
echo "<language>$backend_language</language>\n\n";
$count = 1;
$result1 = sql_query("SELECT topic_id, topic_last_post_id, topic_title FROM ".$prefix."_bbtopics ORDER BY topic_last_post_id DESC LIMIT 15", $dbi);
while(list($topic_id, $topic_last_post_id, $topic_title) = sql_fetch_row($result1, $dbi)) {
$result2 = sql_query("SELECT topic_id, poster_id, FROM_UNIXTIME(post_time,'%b %d, %Y at %T') as post_time FROM ".$prefix."_bbposts where post_id='$topic_last_post_id'", $dbi);
list($topic_id, $poster_id, $post_time)=sql_fetch_row($result2, $dbi);

echo "<item>\n";
echo "<title>".htmlspecialchars($topic_title)."</title>\n";
echo "<link>$nukeurl/modules.php?name=Forums&file=viewtopic&p=$topic_last_post_id#$topic_last_post_id</link>\n";
echo "<guid>$nukeurl/modules.php?name=Forums&file=viewtopic&p=$topic_last_post_id#$topic_last_post_id</guid>\n";
echo "</item>\n\n";

}
echo "</channel>\n";
echo "</rss>";
?>

echo "<description>".htmlspecialchars($backend_title)."</description>\n";
echo "<language>$backend_language</language>\n";
echo "<pubDate>".date('D, j M Y', time())."</pubDate>\n\n";
