Query: An experiment to test the discreteness of time   Time at the Planck scale ($\sim 10^{-44}~\mathrm{s}$) is an unexplored
physical regime. It is widely believed that probing Planck time will remain for
long an impossible task. Yet, we propose an experiment to test the discreteness
of time at the Planck scale and show that it is not far removed from current
technological capabilities.
