Ah, okay, POSIX.1-2024 / IEEE Std 1003.1-2024 / The Open Group Standard Base Specifications, Issue 8 [1] says: "time_t shall be an integer type with a width (see <stdint.h> ) of at least 64 bits" [2]. So in the end `int64_t time_t` only? :-) [1] https://pubs.opengroup.org/onlinepubs/9799919799/ [2] https://pubs.opengroup.org/onlinepubs/9799919799/basedefs/sys_types.h.html -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
