tzdb — Time Zone Database

Static time zone information for tz-rs.

This crate provides all time zones found in the Time Zone Database, currently in the version 2023d (released 2023-12-22).

See the documentation for a full list the the contained time zones: https://docs.rs/tzdb/latest/tzdb/time_zone/index.html

Usage examples

// get the system time zone
let time_zone = tzdb::local_tz().unwrap();       // tz::TimeZoneRef<'_>
let current_time = tzdb::now::local().unwrap();  // tz::DateTime

// access by identifier
let time_zone = tzdb::time_zone::europe::KYIV;
let current_time = tzdb::now::in_tz(tzdb::time_zone::europe::KYIV).unwrap();

// access by name
let time_zone = tzdb::tz_by_name("Europe/Berlin").unwrap();
let current_time = tzdb::now::in_named("Europe/Berlin").unwrap();

// names are case insensitive
let time_zone = tzdb::tz_by_name("ArCtIc/LongYeArByEn").unwrap();
let current_time = tzdb::now::in_named("ArCtIc/LongYeArByEn").unwrap();

// provide a default time zone
let current_time = tzdb::now::local_or(tzdb::time_zone::GMT).unwrap();
let current_time = tzdb::now::in_named_or(tzdb::time_zone::GMT, "Some/City").unwrap();
