Time Interval Period

A Time Interval Period is a contiguous subsequence (an interval) of a temporal dimension with a start time and an end time.

• Context:
  • It can associated with a Time Interval Duration Value.
  • It can be an input or output of a Temporal Function.
  • It can be represented by a Time Interval Record.
• Example(s):
  • a Pause between Spoken Utterances.
  • an Entity Lifetime.
  • a Calendar Day, 2008-Oct-09,
  • a Month-to-Date, Year-to-Date.
  • a Cambrian Life Explosion Period (540MYA to 520MYA).
  • …
• Counter-Example(s):
  • a Time Instant.
  • a Space Interval.
• See: Episodic, Numeric Interval.

  • The term "time" is generally used for many close but different concepts, including:
    • instant as an object — one point on the time axes. Being an object, it has no value;
    • time interval as an object — part of the time axes limited by two instants. Being an object, it has no value;
    • date as a quantity characterising an instant. As a quantity, it has a value which may be expressed in a variety of ways, for example "2014-04-26T09:42:36,75" in ISO standard format, or more colloquially such as "today, 9:42 a.m.";
    • duration as a quantity characterizing a time interval. As a quantity, it has a value, such as a number of minutes, or may be described in terms of the quantities (such as times and dates) of its beginning and end.

  • 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.
