Relation of uncertainty for time

We introduce two time: deterministic Newton time-stream t and stochastic time-epoch $\tau$. The relation of uncertainty for time-epoch of physical events $\Delta\tau\Delta D \geq c_1,\eqno(*)$ where $c_1=const$, is proved. The function $D(t)= - c_1\frac{d}{dt}\ln f_\tau (t),$ characterizes {\it velocity of disorganization} of the event-phenomena; $f_\tau (t)$ is density of probability of time-epoch $\tau$. The relation (*) is verified not by means of experiment that is traditional for physics, but with the help of the reference to datas of historical science.
