Good catch. Per Wikipedia: Lotus Agenda is a "free-form" information manager: the information need not be structured at all before it is entered into the database. A phrase such as "See Wendy on Tuesday 3pm" can be entered as is without any pre-processing. Since that software is from 1992, it would definitely be prior art.
