SQL Server Agent Jobs duration Report

Hi folks. I would like to share with you the following simple script to show us jobs duration report in SQL Server 2005. I manipulated with INTERGER values stored by SQL Server to convert them into DATETIME/CHAR(8) datatypes to represent the data.
Thanks to SQL Server MVP Peter Ward provided me with StartTime calculation.

WITH job_duration_view
AS
(
SELECT name,
StartTime = CONVERT(DATETIME, RTRIM(last_run_date)) +
(last_run_time * 9 + last_run_time % 10000 * 6 + last_run_time % 100 * 10 + 25 * last_run_duration) / 216e4 ,
CONVERT(CHAR(8),DATEADD(ss,last_run_duration,CAST(last_run_date AS CHAR(8))),114)
AS duration
FROM msdb.dbo.sysjobservers js
JOIN msdb.dbo.sysjobs j ON j.job_id = js.job_id
WHERE last_run_date >0 AND last_run_time >0
) SELECT name AS job_name,StartTime,
StartTime -'19000101'+Duration AS EndDate ,Duration
FROM job_duration_view
