The time distribution of relaxation events in an aging system is investigatedvia molecular dynamics simulations. The focus is on the distribution functionsof the first passage time, $p_1(\Delta t)$, and the persistence time,$p(\tau)$. In contrast to previous reports, both $p_1$ and $p$ are found toevolve with time upon aging. The age dependence of the persistence timedistribution is shown to be sensitive to the details of the algorithm used toextract it from particle trajectories. By updating the reference point in eventdetection algorithm and accounting for the event specific aging time, weuncover age dependence of $p(\tau)$, hidden to previous studies. Moreover, theapparent age-dependence of $p_1$ in continuous time random walk with an ageindependent $p(\tau)$ is shown to result from an implicit synchronization ofall the random walkers at the starting time.
