Yes. Is it really dead? If so, that's unfortunate. Anyway, I've sent an
email to their devel list with a patch, and I've opened one up inside Red
Hat since we still ship Heirloom-mailx.
Here's the patch, for kicks, based on what they were saying in the Debian
bug about just using tm_gmtoff. (Which I now see is what you were
referencing in your code snippet at the end.)

Insects have been dying off in great number for a couple decades now, for a
variety of reasons. It's really bad news for us if we can't fix that.
Convincing politicians to change is not nearly as critical as convincing
our neighbors that we're in a really fragile place. I hope my kids aren't
among the last generation of humans because we've implemented our instance
of the Great Filter:

Mm. I learn something every day. I didn't realize the copy of a parameter
passed in by value was free to be manipulated. But sure enough.
