  We analyze the electronic correlation contribution to the time delay in the
photo-ionization of the excited ortho- and para-Helium states. A simple
estimation, based on the ionization probability amplitudes, shows that the
different form of anti-symmetrising both states can in principle lead to very
different values of the correlation time delay. This result illuminates the
interplay between electronic correlations and symmetrisation effects in the
attosecond regime, a relation that has been studied in other contexts.
Moreover, it suggests the potential of excited states to explore the role of
exchange effects in that realm.
