 Hello:
By popular demand, No but just I could bearly read the
output. I did a couple of reads of Microsoft Documents
on the intermet and come up with a Brighter Ouput.

Note the Environmental Variable TZ MUST be SET before
or %Z will not work. SET in DOS i e Command Promt or
Conrol Panel.

I have found out tm_mon is 0 to 11 Not 1 to 12.
Also a program to find your 15 attribute a very short program.

HI C users:

For Quieter Builds and to SHUT UP the compiler try this.
Edit stdafx,h like so. e g

Code Select Expand


// stdafx.h : include file for standard system include files,
// or project specific include files that are used frequently, but
// are changed infrequently
//

#pragma once
#define _CRT_SECURE_NO_WARNINGS
#include "targetver.h"

#include <stdio.h>
#include <tchar.h>



// TODO: reference additional headers your program requires here



It makes for very quiet Builds and kills a lot of warnings!

Enjoy!

Is your code an improvement over the date command ?
