Okay,
I checked Lewine (1991) "POSIX Programmer's Guide" :

POSIX specifies that ctime() has a final "\n"
(before the string terminator \0)
and always length 26 (incl. terminator)

Hence, we have to drop the final "\n",
already in function R_Date() which is [in src/main/platform.c]
currently
    char *R_Date()
    {
        time_t t;
        time(&t);
        return ctime(&t);
    }

How can we drop is this done in the most elegant way?
(without having to allocate a char[26] ?)
