> I'm not sure what a correct system should be, but I know that it can't be based on the Earth, the sun, or any one galaxy. In order to have accurate time, it must be external to all of these things, like a meter stick is to an object.
But Einstein's theory of relativity makes that impossible -- there is no absolute time. The larger reason for debates like this is because any timekeeping convention is relative.
As to a "meter stick", that's also relative, and therefore arbitrary, for the same reason -- relativity theory.
