It's not *that* slowly -- this started less than a week ago <wink>.  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 ...
