Actually I have not found this solution myself, even if I have dealt with this problem for quite a lot of time. But why didn't Einstein mention this solution? My problem was, that I thought about 'local time' and therefore wanted 'A-time' to be named 't' and 'B-time' values 'tau'. So, in my opinion all variables with a 't' are meant as 'A-time' and based on system K. But that wasn't actually Einstein's use of the letter 't'. It was only my impression of Einstein's intentions, because I have read the paper several times and introduced concepts from that paper which occured later also to the beginning, where they do not apply.
