However, in the case of calendrical calculations, reifying a duration
makes a great deal of sense. Representing a duration internally as a
number of seconds makes a great deal less sense though. Consider the
problems inherent in 1.month, daylight savings, leap years, leap
seconds and the whole jujuflop situation that is timezones.
