Since this has not been marked as duplicate, and the response in the main thread is just way clearer IMHO. I'll add it here for more visibility:

It can be done pretty concisely using divmod:

t = (end_time - start_time).round.abs
mm, ss = t.divmod(60)
hh, mm = mm.divmod(60)
puts "%02d:%02d:%02d" % [hh, mm, ss]

You could probably DRY it further by getting creative with collect, or maybe inject, but when the core logic is three lines it may be overkill.

Note that I've changed a bit the answer to fit better this thread's question.
