[Guido, on "naive time"]

... Naive time calculations are easier than local time calculations, because they don't have to worry about DST. You only have to be careful when converting between naive time and UTC (or anything else that has a concept of timezone).

Just to let you know: you are slowly narrowing in on mxDateTime ;-) (the naive type is pretty much what I have implemented as DateTime object).

It's not that slowly -- this started less than a week ago . But, yes, Guido's basic class is heading more in the direction of what mxDateTime started as. By the time you had need of documenting things like

Adding/Subtracting DateTime instances causes the result to
inherit the calendar of the left operand.

I think "naive time" got lost in the options. Guido has in mind a pure "proleptic Gregorian" gimmick. We'll see how long that lasts ...
