  We consider the possibility of measuring non-equilibrium properties of the
current correlation functions at high temperatures (and small bias). Through
the example of the third cumulant of the current (${\cal{S}}_3$) we demonstrate
that odd order correlation functions represent non-equilibrium physics even at
small external bias and high temperatures. We calculate ${\cal{S}}_3=y(eV/T)
e^2 I$ for a quasi-one-dimensional diffusive constriction. We calculate the
scaling function $y$ in two regimes: when the scattering processes are purely
elastic and when the inelastic electron-electron scattering is strong. In both
cases we find that $y$ interpolates between two constants. In the low (high)
temperature limit $y$ is strongly (weakly) enhanced (suppressed) by the
electron-electron scattering.
