Contrast this with POSIX (https://pubs.opengroup.org/onlinepubs/009695399/functions/gmtime.html) whi= ch states that in this case the return should be NULL with errno set to reflect the error. Other libc's (glibc, MacOS, MSVC) also return NULL in this case. For example, time_t val =3D 0x7fffffffffffffffll; gmtime(&val) does not return NULL. This affects my ability to correctly calculate the maximum allowed value of time_t in Samba's configure phase.
