Storing isdst in the datetime object would allow utcoffset(dt) to distinguish between 1:30AM before clock change and 1:30AM after. Where do you propose to store the offset? If you store it in dt, why would you need the tzinfo?

Because otherwise you don't know what tzinfo the datetime uses, and you need to know that if you add or subtract a timedelta, or compare with another datetime.

Regardless, whatever the proposal to add timezones to stdlib will end up being, it must include the ability to implement an equivalent of UNIX date command shown above.

That's a strftime() issue, I think that issue is already solved.
