It's 2:56PM. What time will it be 24 hours from now? If your answer is "not enough information to say, but it will be some minute between 1.56PM and 3:56PM inclusive", you want to call _that_ "naive"? I sure don't. You can only give such an answer if you're acutely aware of (for example) DST transitions. If you're truly naive, utterly unaware of the possibility of occasional time zone adjustments, then you give the obvious answer: 2:56PM. That's what Python's datetime arithmetic gives. That's naive in both technical and colloquial senses. You're only aware of that "2:56PM tomorrow" may be anywhere between 23 and 25 hours away from "2:56PM today" because you're _not_ ignoring possible transitions. So,. sure, I agree that your pointing it out "hardly ignores the transition point". But I wasn't talking about you ;-) I was talking about the arithmetic, which does thoroughly ignore it. _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
