  Dynamics in conformally connected frames are often referred to as
'equivalent'. In the context of cosmology, while the perturbations remain
invariant for a single scalar field model, the background equations differ and
therefore the dynamics. However, since the background dynamics are not the
same, it is not clear whether the attractor nature of the solutions remains the
same in all conformally connected frames, i.e., a stable solution in one frame
implies an equivalent stable solution in another frame. To answer the question,
in this work, we first consider power law cosmology in the Brans-Dicke theory
as well as in the conformal Einstein frame. We show that, in this case, the
attractor behavior is indeed equivalent under conformal transformation, i.e.,
an attractor solution in one frame implies an attractor solution in another
frame. However, the decay rates of the deviations from the fixed points are
different in the two frames. We are able to relate the behavior and find that
the difference is due to the difference in e-fold 'clocks' in different frames,
i.e., $\Delta N$ in different frames differ from one another. We show that the
behavior is indeed true for any model in conformally connected frames and
obtain the general 'equivalence' relation. In the context of inflation, we
consider two models: Starobinsky and chaotic inflation, and explicitly point
out the differences in these two frames. We show that the duration of inflation
in any model in the Jordon frame is always higher than the Einstein frame.
