Debian currently does (https://salsa.debian.org/debian/groff/blob/master/debian/patches/display-utc-times.patch). But I'm unsure about the correctness of this, which is why I hadn't pushed it upstream; it was something of a desperation measure to get reproducible builds working in more places, but changing the semantics of things like \n[hours] is not ideal. Perhaps playing whack-a-mole with TZ=UTC in more places would be better in this case, although it seems unlikely to be much fun - I'm not sure. -- Colin Watson (he/him) [cjwat...@debian.org]
