Thanks for the pointer.

I checked it out (quickly) and as far as I can see:
* times, dates, ranges are all "absolute"
* duration is the only "relative" class
  (and that seems to be a "length of time, expressed in a number of days +
   a number ofpicoseconds").

So, I did not find back the most important aspect of what I need,
a time or a day "relative" to day, week, forthnight, etc.

On top, every range can be cyclical, so there is no <=> operator.

Both the "09:00 until 18:00" and the "20:00 until 06:00" range
are valid (think day time job and night shift). Same for
days: does Monday come before or after Friday? Before if one
thinks "workweek", after if one thinks "weekend".

I plan to continue just with the specific concept of a "relative"
time and then we can see if it makes sense to take on a
broader aspect of "Time management" (pun intended).
