I am just trying to get a human readable output of the result of
(time-subtract ...). I use it for elapsed time. Clearly for such usage
the output could in a strict sense contain only

  days, hours, minutes, seconds

Making a good general function for that seems perhaps a bit tricky
since you may both want to leave out things from the beginning of this
list and specify a format for them. But maybe it can take four
optional format arguments in the reverse order of this list?
