Point in Time (TS)

Timestamps provide a means of marking a specific point in time. For example: a person's birthday, or the time a prescription dispense was recorded, etc.

High-level Timestamp Types

CHI defines four timestamp specialization types:

  1. TS.DATE
  2. TS.DATETIME
  3. TS.FULLDATE
  4. TS.FULLDATETIME
A timestamp can vary from a simple partial date (e.g. only a year) to a fraction of a second in time within a specified timezone. A timezone is given as a relative offset to Coordinated Universal Time (UTC). For example, “-0800” represents the Pacific Time Zone. The Gregorian (Western) calendar is the default calendar.

Specialization Types

Below are the basic rules for using each of the timestamp specification types:
