V.   Occurrence

Instance is the unique experience of a present instant of Ucadian Time by a single observer. A collection of Instances by one or more observers represents an Occurrence.

No two observers may experience Time under exactly the same conditions and location; therefore no two observers will have the precise same experience of an Instant.

The perceived duration of an Instance is relative; the greater the density of objects and interactions, the shorter an Instance will appear; the lesser the density of objects and interactions, the longer an Instance will appear.
