  Haydn, Lacroix and Vaienti [Ann. Probab. 33 (2005)] proved that, for a given
ergodic map, the entry time distribution converges in the small target limit,
if and only if the corresponding return time distribution converges. The
present note explains how entry and return times can be interpreted in terms of
stationary point processes and their Palm distribution. This permits a
generalization of the results by Haydn et al. to non-ergodic maps and
continuous-time dynamical systems.
