Indeed, I'm setting the maximum valid value as specified in the documentation to determine the actual date/time. If you add 1 to that number it returns an Invalid Date exception. I didn't need to loop/test because for once I had actually read the manual! :-D ;-]

assume life -= .5 But don't spend too much time putting that estimate together, I have a funny feeling that this will never quite reach the top of the priority list!!! ;-]
