    "abstract": "We consider a clock \u0027paradox\u0027 framework where an observer leaves an inertial\nframe, is accelerated and after an arbitrary trip comes back. We discuss a\nsimple equation that gives, in the 1+1 dimensional case, an explicit relation\nbetween the time elapsed on the inertial frame and the acceleration measured by\nthe accelerating observer during the trip.\n  A non-closed trip with respect to an inertial frame appears closed with\nrespect to another suitable inertial frame. Using this observation we define\nthe differential aging as a function of proper time and show that it is\nnon-decreasing. The reconstruction problem of special relativity is also\ndiscussed showing that its, at least numerical, solution would allow the\nconstruction of an \u0027inertial clock\u0027.",
