Scope note to be rewritten as follows:
A determination of a range of dates or duration without
any further connotations, to be used to set limits to the temporal extent
of periods, events and any other phenomena valid for a certain time. A
time appellation is a verbal form which refers to a time-span. The time-span
itself is a temporal extent in the sense of Galilean physics. Different
time-appellations may express the same time-span. The Time-Span represents
the real extent of the entity it refers to, which is always fuzzy to a
certain degree and only known in approximation. Respective properties
of Properties of time-span allow the expression of approximations of a
time-span according to our knowledge.
