The Time delta is only known if both the times are on the same day. Essentially, a diff is only valid for DateTime objects
It depends on which day the times a and b are on. If they're on the same day then you could say:
Time a := ...; Time b := ...
Date today := Date.now
Duration c := a.toDateTime(today) - b.toDateTime(today)
If a and b are on different days then you need that date information to know if the duration is +'ve or -'ve.

Yeah its really designed that differences in time are done with a DateTime and not just a Time. I've quite a ton of time based code, I definitely think that is typically how you want it to work. But if you really want to subtract two Times, then you can do this:
fansh> a := Time(13, 0)
13:00:00
fansh> b := Time(5, 0)
05:00:00
fansh> a.toDuration - b.toDuration
8hr

Am I missing something?
I can't say:
