Definitions
In plain terms
New York market time changes its UTC offset during daylight-saving transitions, so a fixed offset is not enough for historical scheduling.
Technical
Store a named IANA zone plus the tzdb version when reproducibility matters; an offset identifies one instant but not the zone's historical or future rules.
Scope
A time-zone database does not define exchange holidays or sessions.
Examples
- A governed dataset records time zone explicitly instead of inferring it from an ambiguous field.
Common misconceptions
- Time Zone does not have one universal meaning without its stated market, source, and time context.
