This repo contains the IANA time zone database with corresponding modifications to enable it to work in the Fantom runtime.
We maintain a copy of the original database in the <version>-orig/ directory. The <version>/ directory contains our
modifications for the Fantom time zone database.
Starting with the 2025c release, you will find a <version>/diffs/compare.txt file that details the notable changes
between the current version and the previous version. This file is generated by the ./compare.fan script.
To actually generate the time zone database for Fantom (JVM and JS runtimes), you need a Fantom distribution and
must run the adm/buildtz.fan script. That script expects to find this repo in your $HOME directory so you
should clone this repo to your $HOME dir.
