    • There are two kinds of temporal entities -- instants and intervals.
      • (1)(forall (t) (if (instant t)(temporalEntity t)))
      • (2)(forall (t) (if (interval t)(temporalEntity t)))
    • No assumptions are made about whether intervals _consist_ of instants. Rather one can specify relations between the two, such as that an instant begins or ends or is inside an interval.
