Time zone boundaries (timezone-boundary-builder 2026c)

Licencia: ODbL 1.0 (texto de la licencia)

Time zone suggestions use boundary data © OpenStreetMap contributors, ODbL 1.0, via timezone-boundary-builder 2026c. The time zone printed on a sheet is the one its buyer selected from the public-domain IANA time zone database.

⚠ COUNSEL: review of the ODbL produced-work severance argument (user-confirmed selection off public-domain tzdata), and whether compiling the boundary data into the binary constitutes conveying the database. Both are owed before the first paid sheet.

LocationIQ

Licencia: Vendor terms of service (texto de la licencia)

Geocoding and map tiles by LocationIQ. Location data © OpenStreetMap contributors, ODbL 1.0.
