After much head-scratching: _proleptic_ POSIX TZ offsets[1] do indeed tend to
refer to more-Westerly locations as the offset values increase in the positive.

Back on-topic: I had briefly proposed a merge request on Salsa to use a fixed
TZ=UTC setting during package testing via debian/rules -- but after further
consideration, I've spent more time investigating the upstream codebase and
have offered a possible fixup there (annotated as the forwarded URL for this
bug).
