There was no ftime() everything was compiled into libc which in 6th edition contained the line: int timezone 5*60*60; which we'd write in modern C as int timezone = 5 * 60 * 60; That was for US Eastern time, and shows a positive timezone being used to mean west of Greenwich. I think it was that way in 5th edition as well - before then is before my time. kre
