I note that the macOS (15.6) manual includes the caveat: The file generation number, st_gen, is only available to the super-user. I don't know if that applies to the *BSD releases. I don't know how much of a problem that is for the proposed TZ code. On Sun, Oct 5, 2025 at 8:10 PM Guy Harris via tz <tz@iana.org> wrote:

macOS also checks struct stat's st_gen, which is easy and seems like a good idea on platforms that have st_gen.
So all the 4.4-Lite derivatives, i.e. (Free,Net,Open,DragonFly}BSD as well as Darwin, and maybe others.
