Perhaps something more like this:

SELECT

j.job_id,

s.srvname,

j.name,

js.step_id,

js.command,

j.enabled ,

js.last_run_date,

js.last_Run_Time,

js.last_run_duration,

msdb.dbo.Agent_datetime(js.last_Run_Date, js.last_Run_Time) AS Run_Datetime,

dateadd(second, ((js.last_run_duration / 10000) * 3600) + (((js.last_run_duration / 100) % 60) * 60) + (js.last_run_duration % 60), msdb.dbo.Agent_datetime(js.last_Run_Date, js.last_Run_Time)) as EndRunDate

FROM

dbo.sysjobs j

JOIN dbo.sysjobsteps js

ONjs.job_id = j.job_id

JOIN master.dbo.sysservers s

ONs.srvid = j.originating_server_id

WHERE

j.name = 'TestJob';
