If the answer is that we need to make 3 decisions and do the C implementation, that seems feasible to do in under a month. If the answer is that we've got 10 contentious UI issues and we probably want to go through the PEP process, I agree with your assessment of the timing.

To be honest, I don't find this very compelling and I think it will only confuse people. I think most people use `timedelta` to represent something you add or subtract to a `datetime`. Having the `nanoseconds` part of it truncate seems like it would be frustrating and counter-intuitive. >From the use cases in this thread: - ns-precision timestamps: https://bugs.python.org/issue15443#msg180125 - ns-precision timestamps: https://bugs.python.org/issue15443#msg223039 - Your suggestion that `datetime` should be able to support what `timespec` does: https://bugs.python.org/issue15443#msg223042 - ns-precision timestamps: https://bugs.python.org/issue15443#msg270266 So I don't think there's high enough demand for nanosecond-timedelta on its own that we need to rush it out there before datetime gets it. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue15443> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
