Given any line from a plain-jane errpt dump, this routine will parse out and rebuild the timestamp into something a bit more recognizable. Since errpt doesn't have per-second resolution, I just throw an ":00" at the end of the string. The form that $errorTimeStamp takes is actually SQL type-compliant to DATETIME. :) 
sub figureOutDateOfLogEntry
{
        $itemMeridian="AM";

        ($logEntry)=@_;
        $itemMonth=substr($logEntry,11,2);
        $itemDay=substr($logEntry,13,2);
        $itemHour=substr($logEntry,15,2);
        $itemMinute=substr($logEntry,17,2);
        $itemYear=substr($logEntry,19,2);
        $itemResource=substr($logEntry,26,7);
        $itemType=substr($logEntry,41,20);
        chomp($itemType);

        if($itemHour>12) { $itemMeridian="PM"; $itemHour-=12; }

        $errorTimeStamp="20".$itemYear."-".$itemMonth."-".$itemDay." "
+.$itemHour.":".$itemMinute.":00";
}
