geotz 0.0.2b0

Simple library for offline lookup of the timezone for a location.

GeoTZ v0.0.2b0

Docs: https://geotz.readthedocs.io/

This is a small library for looking up the timezone for a given country code and postal code / postal code prefix. The main logic under geotz is very small indeed, so you can easily read it for yourself.

It’s well tested - see the coverage badge above and take a look at the tests for all the cases that are covered.

Compared to alternatives like geopy or pgeocode, it’s intended to be easier to use, less feature rich, and more lightweight.

It uses offline data from www.geonames.org to find the approximate location and then uses another library to convert that into a timezone.

Please read the LICENSE file for important information about using this library and the data contained within.

Motivation

1. Easy to use. No API key or external API service required.

2. Fast offline lookup.

3. No downloads required; the necessary data comes bundled with the package.

4. No network requests.

5. I tried to keep the extra dependencies to a minimum.

6. Data is loaded from disk on demand, so as to not use unnecessary memory.

Development

To run the build, there’s the GitHub actions workflows as well as the option to run locally.

For running the build locally, use pip install tox and the run tox in the repository base directory (or tox -p to run the build in parallel).

1. Ensure you have tox installed e.g. by running pip install tox

2. Extract data tox -e extract_data

3. Run the build: tox
