That's only approximately true. Some days contain 25 or 23 hours (consider
the days where daylight savings switches over), and when a leap second is
introduced, a minute can contain 61 seconds or a day can contain 86401
seconds. Context (an absolute date) is needed to perform these duration
calculations correctly.
