This won't be hard at all.

In newreply.php

Find:

$DB_site->query("UPDATE forum SET replycount=replycount+1,lastpost='".time()."',lastposter='".addslashes($postusername)."' WHERE forumid IN ($foruminfo[parentlist])");

Replace With:

$threadstarttime=$DB_site->query_first("SELECT dateline FROM thread WHERE threadid='$threadid'");
$DB_site->query("UPDATE forum SET replycount=replycount+1,lastpost=$threadstarttime,lastposter='".addslashes($postusername)."' WHERE forumid IN ($foruminfo[parentlist])");
