explain_time_or_die - get time in seconds and report errors
time_t explain_time_or_die(time_t *t);
time_t explain_time_on_error(time_t *t);
The explain_time_or_die function is used to call the time(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_time(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_time_on_error function is used to call the time(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_time(3) function, but still returns to the caller.
The explain_time_or_die function only returns on success, see time(2) for more information. On failure, prints an explanation and exits, it does not return.
The explain_time_on_error function always returns the value return by the wrapped time(2) system call.
The explain_time_or_die function is intended to be used in a fashion similar to the following example:
time_t result = explain_time_or_die(t);
