Chicken 2.6 has inconsistent meaning for timezone offset across
platforms. 2.61 fixed this.
Provided you are not using MacOS X or Windows you can get the current
version (2.6.9) which skips the requirement otherwise.
Well, I was in a rush, so I've wrapped strftime(). This might actually
be useful to others, so I'm posting it. I've used SWIG, but I'm sure
it's trivial using the Chicken FFI (which I don't know though):
#include <time.h>
#include <stdlib.h>
#include <string.h>
// See strftime(3) manpage for format string
char *system_time (const char *fmt) {
time_t t;
struct tm tm;
time (& t);
localtime_r (& t, & tm);
char buf [500];
size_t ret = strftime (buf, sizeof (buf), fmt, & tm);
if (ret == 0) return NULL;
else {
char *res = malloc (ret + 1);
memcpy (res, buf, ret + 1);
return res;
}
}
