    "abstract": "Through the analysis of the definition of the duration of proper time of a\nparticle given by the length of its world line, we show that there is no\ntransitivity of the coordinate time function derived from the definition, so\nthere exists an ambiguity in the determination of the duration of the proper\ntime for the particle. Its physical consequence is illustrated with quantum\nmeasurement effect.",
