ABSTRACT

Suppose that Peter Pim is in his jet plane from Los Angeles to New York and he is asked during his trip what time it is. If he were giving his answer precisely, Peter would not only read his watch but provide a time judgement related either to Los Angeles and/or New York time. Without doubt, clock time depends on his spatial time “frame of reference”. In this book, however, the frame-of-reference concept has a different, more special meaning (see chapter 1, pp. 8-9, see also Baird, 1970; Yonas, 2003).
