Hello -=jugggernut=-.

 I've been working on a not too dissimilar project with ke Neehr
TakeThisOuTneehrspam@spam@swipnet.se , so I can possibly help you with code.  You
might just ask him if he minds if I give you the code.

 I'm not sure what sort of error you mean.  Care to explain?  I have
coded the clock to work with no error using a 4 MHz crystal.

 You don't need *any* interrupts for this project.  Not only do you not
*need* them, you will find them a great hindrance.
