That's probably as close as you can get ..

The problem with this is that you'd really want to use something other
than DateTime::Duration as DT:D is designed for Date math.
DT:D Proposal
(11 hours, 90 minutes) 750m 11h 90m
+
(32 minutes) 32m 32m
=
782m 11h 122m
* 2 1564m 22h 244m
...
The more we do, the more confusing your proposed method gets. Sure you
could keep it separate inside DT:D but then you'll have to do the math
for both the current and the proposed values every time.
I'd be thinking of just storing the values as a hash(ref) that you later
feed back into DT:D when you need to. That way you can store it however
you need to.
(Personally, I'd be happy as a user if I asked for 90m if it returned
1h30m .. but I imagine different things need different units)
Cheers!
