Einstein gets us coming and >going :-} Actually, you can adjust for relativity. The scalar value 2 2 2 2 x + y + z - (ct) is a constant for all observers, where x, y, and z are the rectangular coordinates from an agreed upon reference point, c is the speed of light, and t is the measured time of an observed event. Throw the appropriate scale and offset factors in and Voila!, you have a stardate. Jon Biggar {allegra,burdvax,cbosgd,hplabs,ihnp4,sdccsu3}!sdcrdcf!jonab
