Detailed Description

Class representing a duration.

This is intended for administrative applications, e.g. adding a duration of 24 hrs to a Date will result in the next day, same time, even if a daylight savings time switch happens in the period.

There are 3 incompatible units:

• seconds (and minutes, hours, days, weeks).
• months (same reasoning as above).
• years (idem)
