I was working on a GenericYear that was intended to be used for DateAndTime calculus - to be able to add and subtract an arbitrary number of years. The class by itself would not know the days - it is an arbitrary (generic) Year.
It would only know the number of days when it is added (or subtracted) from an actual date (or timespan). The idea was that it would have a very specific and limited scope of responsibility.
I liked it. Hopefully a few loose ends can be fixed up so it can be put into trunk.
This one should be better addYears: integer ^ Date year: self year + integer month: self monthIndex day: ((self monthIndex = 2 and: [self dayOfMonth = 29 and: [(Year isLeapYear: self year) and: [(Year isLeapYear: self year + integer) not ]]]) ifTrue: [ 28 ] ifFalse: [ self dayOfMonth]) -- Dr. Geo - http://drgeo.eu iStoa - http://istoa.drgeo.eu
