The first-passage-time statistics of a stochastic process N(t) for electrons transferred through a metallic double dot are considered. It is shown that in calculating the average of the first-passage time, it is necessary to take into account the changes in entropy occurring during this process. Using the example of a DC bias voltage, the influence of external influences on the average first-passage time is considered. All real physical processes, including of the first-passage time, occur with changes in entropy. This circumstance is not taken into account in studies of the first-passage time, but is illustrated in this paper by the example of electrons transfer through a metallic double dot.
