Currently, there is no name used in the literature to describe the incomplete temporal information associated with an event. The modifier ``incomplete'' is too vague (-E9), while ``fuzzy'' has unwanted connotations (i.e., with fuzzy sets) (-E9). ``Indeterminate'' is more general than ``imprecise;'' imprecise commonly refers to measurements, but imprecise clock measurements are only one source of indeterminate events.
