    "abstract": "We study the behavior of clocks in 1+1 spacetime assuming the relativity\nprinciple, the principle of constancy of the speed of light and the clock\nhypothesis. These requirements are satisfied by a class of Finslerian theories\nparametrized by a real coefficient $\\beta$, special relativity being recovered\nfor $\\beta=0$. The effect of differential aging is studied for the different\nvalues of $\\beta$. Below the critical values $|\\beta| =1/c$ the differential\naging has the usual direction - after a round trip the accelerated observer\nreturns younger than the twin at rest in the inertial frame - while above the\ncritical values the differential aging changes sign. The non-relativistic case\nis treated by introducing a formal analogy with thermodynamics.",
