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.
