The problem is, if the functions are enhanced in the current numpy,
then scikits.timeseries is not (yet) available.

I agree that for any more extended finance package, the handling of
"time"series (in calender time) should make use of scikits.timeseries
(and possibly the new datetime array type.)

Pierre, your not already hiding by chance any finance code in your
timeseries scikit? :)


BTW: here are the formulas for the NotImplementedError
