Could you add a test where this goes over a DST transition?

good catch. when we cross a DST transition, dti.freq is actually wrong bc of the (deprecated) kludge in generate_range. As a result, inheriting the freq is incorrect in this case. But it will return to being correct once the deprecation is enforced.
i think the thing to do is add the test and xfail it
