Here's a test program you can copy into a file named test.c and compile it
with "cc -o test test.c". I've included my Solaris output below the
program, so you can compare.
#include <sys/types.h>
#include <stdio.h>
#include <time.h>
void main()
{
int strsize = 255;
time_t timeAsNumber;
struct tm *temp;
char str[256];
timeAsNumber = time(NULL);
temp = localtime( &timeAsNumber);
strftime (str, strsize, "a: %a", temp);
printf ("%s\n", str);
strftime (str, strsize, "A: %A", temp);
printf ("%s\n", str);
strftime (str, strsize, "b: %b", temp);
printf ("%s\n", str);
strftime (str, strsize, "B: %B", temp);
printf ("%s\n", str);
strftime (str, strsize, "c: %c", temp);
printf ("%s\n", str);
strftime (str, strsize, "C: %C", temp);
printf ("%s\n", str);
strftime (str, strsize, "d: %d", temp);

strftime (str, strsize, "D: %D", temp);
