I think that is supported, I already wrote an C code to test it:

#include <stdio.h>
#include <time.h>
#include <locale.h>

int main()
{
  time_t tiempo;
  char cad[80];
  char *old_locale;
  struct tm *tmPtr;

  setlocale(LC_ALL, "es_AR.utf8");
  tiempo = time(NULL);
  tmPtr = localtime(&tiempo);
  strftime(cad, 80, "%H:%M.%S, %A de %B de %Y", tmPtr);

  printf("%s\n", cad);
  return 0;
}

"11:30.08, miércoles de noviembre de 2010"

(But sorry, I don't understand what is date(2), C, scheme, in the term?)

Great! it works!.

Thanks,
