Summary
Following the previously postponed rollout, the Public API is moving forward with an update to align time zone formatting with the modern IANA time zone identifier convention.
This change replaces the older Olson-style short format with the current IANA format to improve accuracy and reflect modern time zone standards, including changes in daylight savings observance across different regions.
For example:
- New format: America/New_York
Effective Date
Monday, June 8, 2026
Details
Date and time formatting standards are continually evolving. To provide a better user experience and maintain accuracy, we are updating our API to follow the modern IANA time zone identifier format. This standard moves away from the shorter, original time zone formats.
You can find the latest IANA tz database information here: Time Zone database
Customer Impact
Customers consuming API responses will observe a change in the format of the timeZone response fields. Time zones will now be represented by city name instead of the previous short format.
For example, EST5EDT will now appear as America/New_York in API responses.
Users who rely on the previous short format may need to adjust their applications to accommodate this change.
