vtimezones-rs

Provides timezones from the IANA TZDB as VTIMEZONES for the iCalendar format.

Uses the timezone data from https://github.com/eggert/tz/ and https://github.com/libical/vzic for conversion.

Exports

pub static VTIMEZONES: phf::Map<&'static str, &'static str>;
pub const IANA_TZDB_VERSION: &str = "2025b";

This project is not affiliated with any of its dependencies.

Building

• Run make to compile the timezones to ics
• Run cargo build

The compilation is not included in build.rs because then gtk (which is a vzic dependency) would need to be available on any machine wanting to compile this crate.

Updating TZDB

• git -C tzdata checkout <new version>
• Update IANA_TZDB_VERSION in src/lib.rs
• Update IANA_TZDB_VERSION in README.md
• Run make
