About provides access to an API for obtaining a time zone by geographic coordinates. Geo data extracted from OpenStreetMap.

API version

0.0.3a (12.12.2023) - fixed issues, added several missed IANA zones from previous import and ISO 3166-1 country names.

0.0.2a (12.10.2023) - implemented support for time zones based on the IANA database. The accuracy of determining time zones based on abbreviations has been improved. Also added country code based on ISO 3166-1.

0.0.1a (19.09.2023) - initial MVP-1 deploy. In this version, about 80% of the territory is covered, completely excluding Antarctica region. Locations where the time zone does not match with the administrative border, the time zone is selected based on the greatest coverage.
