Since durations are only based on timespans of fixed lengths, they do
not work relatively. So there is no time-detection magic to determine
the days in a given month, because also durations don't distinguish
between what month it is (whether it be January or Feburary).
BigDuration, the class that supports years and months will assume 30
days as 1 month, and 12 months as 1 year.
