But my point if that given datetimestamp or calculation could be off by a second or so depending on whether and how leap seconds are implemented. It just doesn’t seem like a good idea to be handling months and femptoseconds with the same “encoding” -CHB _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
