   nature of the second law & corr. entropy flows, fluctuations fundamentally
   limit the performance of any clock. This suggests a deep relation between the
   increase in entropy & the quality of clock ticks. Indeed, minimal models for
   autonomous clocks in the quantum realm revealed that a linear reln can be
   derived, where for a limited regime every bit of entropy linearly increases
   the accuracy of quantum clocks. But can such a linear relation persist as we
   move toward a more classical system? We answer this in the affirmative by
   presenting the first experimental investigation of this thermodynamic reln in
   a nanoscale clock. We stochastically drive a nanometer-thick membrane & read
   out its displacement with a radio-freq. cavity, allowing us to identify the
   ticks of a clock. We show theoretically that the max. possible accuracy for
   this classical clock is proportional to the entropy created per tick, similar
   to the known limit for a weakly coupled q.clock but with a different
   proportionality const.. We measure both the accuracy & the entropy. Once
   nonthermal noise is accounted for, we find that there is a linear reln
