Definitions
In plain terms
A symbol-change notice can be published today but become effective at tomorrow's market open. Effective time records the latter boundary.
Technical
Effective time belongs to valid-time modeling and should be stored separately from publication, ingestion, and revision timestamps.
Scope
The source must define boundary inclusion and the relevant calendar or time zone.
Examples
- A governed dataset records effective time explicitly instead of inferring it from an ambiguous field.
Common misconceptions
- Effective Time does not have one universal meaning without its stated market, source, and time context.
