This function makes me really nervous, because it's a naive datetime rather than a tz-aware datetime. Could we do better about preserving the exact point-in-time value of the tz-aware time information?

("no" is a possible answer here, but I'd really like to know why we're not storing the zone offset in the datetime object.)
