Now that other solar systems have been discovered, as well as binary and trinary star systems, is the helio-geocentric Astronomical Unit still useful? Wouldn't it be clearer to use the terms light second, light minute. light day, light year, etc., instead? Obviously, these terms are still based on earthbound astronomical measurements for their time unit designation, but, seeing I can think of no rational basis for a universal time unit, it seems that clarity of presentation should prevail in deciding this matter.
