EXAMPLES
     The following example uses nl_langinfo() to obtain the date and time for-
     mat for the current locale:

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

           int main(void)
           {
                   char datestring[100];
                   struct tm *tm;
                   time_t t;
                   char *ptr;

                   t = time(NULL);
                   tm = localtime(&t);
                   (void)setlocale(LC_ALL, "");
                   ptr = nl_langinfo(D_T_FMT);
                   strftime(datestring, sizeof(datestring), ptr, tm);
                   printf("%s\n", datestring);
                   return (0);
           }
