Methods from the theory of averaging of nonlinear dynamical systems are used to prove that time-dependent systems and their corresponding time-averaged versions have the same late-time dynamics. Therefore, simple time-averaged systems determine the future asymptotic behavior. Depending on values of barotropic index  $$\\gamma $$  <math> <mi>\u03b3</mi> </math>   late-time attractors of physical interests for LRS Bianchi III metric are Bianchi III flat spacetime, matter dominated FLRW universe (mimicking de Sitter, quintessence or zero acceleration solutions) and matter-curvature scaling solution. For open FLRW metric late-time attractors are a matter dominated FLRW universe and Milne solution. With this approach, oscillations entering nonlinear system through Klein\u2013Gordon (KG) equation can be controlled and smoothed out as the Hubble factor H \u2013 acting as a time-dependent perturbation parameter \u2013 tends monotonically to zero. Numerical simulations are presented as evidence of such behaviour."
