Right, that should work. In my 2020 experiment I did the opposite and actually patched glibc to remove the time32 interfaces so I could be really sure that everything would use the time64 path, but clearly at least the core packages all use the buildflags correctly. > Hmm.

Adelie Linux has (had?) a great summary. I can't reach the wiki page at the moment, but I found an archive copy at https://web.archive.org/web/20220301175235/https://wiki.adelielinux.org/wiki/Project:Time64 Arnd
