jetblack-tzdata

A builder for timezone data.

This is work in progress.

Overview

This is a re-implementation in Python of the JavaScript build scripts from moment-timezone for exporting IANA timezone data to JSON format.

Installation

The resulting package can be installed from npmjs.

npm install --save @jetblack/tzdata

Usage

See @jetblack/date for usage instructions.

Development

To build the package, first install it to a virtual environment with poetry. Then run build-tzdata. This will create the packages in the package folder. The package can then be published to npmjs.

Note: The version in package/package.json must be updated manually.

python3 -m venv .venv
. .venv/bin/activate
poetry install
