The class Duration allows to define durations in years and months and can be used as limited replacement for timedelta objects. iÿÿÿÿ(t timedelta(tDecimalt ROUND_FLOORcCsP||||}}||jtƒ}|||}||7}t|ƒ|fS(s- A divmod function with boundaries.

The difference to datetime.timedelta is, that this class handles also differences given in years and months. A Duration treats differences given in year, months separately from all other components. A Duration can be used almost like any timedelta object, however there are some restrictions: * It is not really possible to compare Durations, because it is unclear, whether a duration of 1 year is bigger than 365 days or not. * Equality is only tested between the two (year, month vs. timedelta) basic components. A Duration can also be converted into a datetime object, but this requires a start date or an end date. The algorithm to add a duration to a date is defined at http://www.w3.org/TR/xmlschema-2/#adding-durations-to-dateTimes ic Cst|tƒs$tt|ƒƒ}nt| tƒsHtt| ƒƒ} n||_| |_t|||||||ƒ|_dS(sN Initialise this Duration instance with the given parameters.
