No, it has nothing to do with conversions. The difference between a naive timezone and a UTC one is that the UTC one explicitly specifies that it's UTC and not "local time" or some other assumed or unknown timezone. This can make a big difference when passing datetime objects to third-party libraries, such as database interfaces. _______________________________________________ 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
