Thanks for the heads-up. I'm inclined to guess that the December 20 transition will be at midnight standard time, not midnight DST, as that's been their common pattern for fall-back transitions. It's a guess either way, of course, but here's a proposed patch. I've pushed this to the experimental github repository. Sounds like it's time for a new release soon.
