Timezone boundary data
----------------------

This skill resolves a timezone from coordinates using the `timezonefinder`
package, which obtains its boundary database from the separate
`timezonefinder-data` distribution:

    https://github.com/jannikmi/timezonefinder

That database is built by the timezone-boundary-builder project from
OpenStreetMap data:

    https://github.com/evansiroky/timezone-boundary-builder
    https://www.openstreetmap.org/copyright

It is licensed under the Open Database License (ODbL) v1.0:

    https://opendatacommons.org/licenses/odbl/1-0/

This distribution contains none of that database. `timezonefinder-data` is an
ordinary dependency: pip installs it from its own package, which carries the
data and the ODbL terms, and the skill queries it in place, unmodified. The
credit above is given because the ODbL asks for attribution wherever the data
travels, and because the terms have been accepted for this dependency rather
than merely tolerated.

The ODbL's share-alike clause binds a derivative of the database. Anyone who
alters the boundary data and passes it on must offer the altered database under
the ODbL. Using this skill, or building on its Apache-2.0 code, creates no such
obligation.
