How to display aggregated time values in hh:mm:ss format?

I need to aggregate time values at different hierarchy levels: time spent on a lesson, a course (multiple lessons), a training (multiple courses).
The data is stored in a MySQL column with data type TIME.
I first tried to aggregate by using SUM on the value, but it does not work.
So I add the TIME_TO_SEC function to my SQL request. Then I get all times in seconds and the SUM function works fine.
But I need to present the result in hours:minutes:seconds format.
My users want to read 01:30:25 and not 5425.
How can I do that? For instance, is it possible to use custom Javascript to format the cells?
Or is there another way of doing this?
