Now that I think about this, wouldn't be better if, after the eventual introduction of the new datetime types in NumPy, the matplotlib would use any of these three and throw away their current datetime class? [Unless they have good reasons for keeping their epoch and/or scale] Cheers, -- Francesc Alted _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
