You're talking about POSIX (a standard) here, and then about "reading the code",
which seems to refer to a specific implementation.

I tried to infer one from the other, I found POSIX to be ambiguous at best

https://pubs.opengroup.org/onlinepubs/009695399/functions/strftime.html

https://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap07.html#tag_07_03_05 (for alt_digits)

https://pubs.opengroup.org/onlinepubs/000095399/basedefs/xbd_chap07.html (for digits)

The code I was referring at was that of glibc, which I meant to provide a link for https://code.woboq.org/userspace/glibc/time/strftime_l.c.html#90do_number (for reference).

I also tried the libc available on mac which is not glib and it exposes the same behavior.

Are you saying that the POSIX standard prescribes to ignore the locale
for non-O format specifiers, or are you saying that the specific
implementation you looked at ignores the locale for non-O
specifiers, presumably in violation of the POSIX standard?

Talking about the POSIX standard

> In fact, it never uses the digits property at all! Neither does printf

The POSIX standard or the implementation you looked at?

POSIX - very explicitly in this case https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap05.html#tag_05
