A Duration object is created either by giving the number of nanoseconds explicitly or a string representation of a Duration.
The Duration object assumes the following definitions:
A year = 52 weeks and 1 day OR 365 days
A week = 7 days
A day = 24 hours
A hour = 60 minutes
A minute = 60 seconds
A second = 10e9 nanoseconds
