Date Handling

Date Handling#

All Date information within the API is expressed in the GMT time zone.
This decision is based on the fact that the API can be invoked by providers from anywhere in the world, and it is not possible to reliably determine their local time zone at the time of the request.
Using a single reference time like GMT ensures consistency and uniformity in the data, preventing ambiguities related to different time zones.
Time Zone
API users are therefore responsible for converting dates to their desired time zone if needed.
