The goal of this project is to produce a shapefile with the boundaries of the world's timezones using OpenStreetMap data.

The code does query the publicly available Overpass API, but it self-throttles the making of requests to have a minimum of 4 seconds gap between requests. If the Overpass API throttles the download, then the gap will be increased exponentially.

As of release 2020a, it is possible to run the script with the underlying input data that was used to build the timezone geometries at the time of the release. In the release files, the `input-data.zip` will have all of the necessary input data including the downloaded files from overpass, the `timezones.json` file and the `osmBoundarySources.json` file as well.

## Limitations of this project

The data is almost completely comprised of OpenStreetMap data which is editable by anyone. There are a few guesses on where to draw an arbitrary border in the open waters and a few sparsely inhabited areas. Some uninhabited islands are omitted from this project. This project does include timezones in the oceans, but strictly uses territorial waters or Etc/GMT timezones instead of unofficially observed areas such as Exclusive Economic Zones.
