Seems I tracked down this annoying bug finally, I think...
in: postbit_display_complete
where
PHP Code:
$lv_vb_eventforums_postTitle .= vbdate($vbulletin->options['dateformat'],
$lv_vb_eventforums_event['dateline_from'], false, true, false, true);
put
PHP Code:
$lv_vb_eventforums_postTitle .= vbdate($vbulletin->options['dateformat'],
($lv_vb_eventforums_event['dateline_from'] + (3600 * $lv_vb_eventforums_event['utc'])) , false, true, false, true);
I saw and corrected this in a few places, all of the plugins that related to the title.
