Sam, According to me: - Observations have in reality points in time or ranges attached to it - As do Evaluations about processes in the patient system they have in reality times attached to them. Inferences are made at a point in time, but relate to inferred processes that come and go, or are believed to be present, or not, during a period of time. - As do Instructions - As do Actions
Time is never is a discriminating factor that sets Observations apart from the other Entry types.
