On the elementary level, electronic current consists of individual electrontunnelling events that are separated by random time intervals. The waiting timedistribution is a probability to observe the electron transfer in the detectorelectrode at time $t+\tau$ given that an electron was detected in the sameelectrode at earlier time $t$. We study waiting time distribution for quantumtransport in a vibrating molecular junction. By treating the electron-vibrationinteraction exactly and molecule-electrode coupling perturbatively, we obtainmaster equation and compute the distribution of waiting times for electrontransport. The details of waiting time distributions are used to elucidatemicroscopic mechanism of electron transport and the role of electron-vibrationinteractions. We find that as nonequilibrium develops in molecular junction,the skewness and dispersion of the waiting time distribution experiencestepwise drops with the increase of the electric current. These steps areassociated with the excitations of vibrational states by tunnelling electrons.In the strong electron-vibration coupling regime, the dispersion decreasedominates over all other changes in the waiting time distribution as themolecular junction departs far away from the equilibrium.
