Convert Time stored in milliseconds integer to hh:mm datetime SQL Server

In a table of scheduled jobs, the JOB_START_TIME is mysteriously stored in milliseconds counting from midnight as data type integer.

I need help to convert these values to hh:mm datetime format so I can make a user-friendly excel report of all the scheduled jobs.

If I don't convert JOB_START_TIME to NUMERIC or DECIMAL, it truncates the time so it is only accurate up to the hour:
SELECT JOB_NAME, MAIL_SERVER, TASK_SERVER, ((((JOB_START_TIME/1000))/60)/60) AS [START_TIME]

So I converted it and what I got was the hour plus a decimal portion representing the fraction of the hour but I don't know how to render that all accurately in hh:mm datetime format:
SELECT JOB_NAME, MAIL_SERVER, TASK_SERVER, ((((CONVERT(NUMERIC,JOB_START_TIME)/1000))/60)/60) AS [START_TIME]

Experts, can you help me get this into a single SQL statement without temp tables, functions, or variables?  I've had difficulty running T-SQL containing the aforementioned from Excel 2003.  Other reporting systems are also not an option.

Thanks!

Hours and minutes?

Select Left( Convert(varchar(10), DateAdd(ms, your number here, Convert(DateTime, '1/1/2000')), 8), 5)

Try this:  
-- add the milliseconds to an arbitrary date
-- convert this format to HH:MM:SS


SELECT JOB_NAME, MAIL_SERVER, TASK_SERVER, convert(char(8), dateadd(ms, JOB_START_TIME, '2001-01-01'), 8) AS [START_TIME]

Or this:

SELECT RIGHT('0' + CAST(JOB_START_TIME / 1000 / 60 / 60 AS varchar(2)), 2) + ':' + RIGHT('0' + CAST(JOB_START_TIME / 1000 / 60 % 60 AS varchar(2)), 2)

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Mastoo and ScottPletcher, both your methods are working perfectly in SQL and Excel!  Only one thing I forgot to mention, it is putting the time in 24hr format.  Can we get it in 12 hour format with AM and PM?  OR is that a separate question?

tlovie: your method is working also, just don't need seconds and need to get it in 12 hour time format.

Try this:

SELECT JOB_NAME, MAIL_SERVER, TASK_SERVER, substring(convert(varchar(20), dateadd(ms, JOB_START_TIME, '2001-01-01'), 100), 12, 8) AS [START_TIME]

Thanks tlovie...that is just about perfect... Is it possible to add a space between the mm and the AM/PM indicator?

tlovie, if you want to comment on the question about spacing please do, but I've already given you credit for the answer since it solves my original issue completely, cosmetics aside.  Thanks to all Experts!!
