Ok

That seems to be possible, too.

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.
