There is nothing readily available. Let's consider that you have
a duration of 1 month, and you want to quarter of it. What should
it be? Well, I guess it depends on what you want to do with that
duration. If it's to be added to a date, then the result depends
on that date. In that case I would suggest turning the duration
into a definite duration (using `to_definite'). Then turn it into
a number of milliseconds (days * milliseconds_in_days +
millisecond_count). Then you can divide by 4 and create a new
date-time-duration using `make_precise_canonical_definite'.
