time-tz

An implementation of the tz database for the time-rs Rust crate.

This implementation is based off of chrono-tz (https://github.com/chronotope/chrono-tz) but uses time-rs instead of chrono. This is designed to replace use of chono dependency which is impacted by CVE-2020-26235 (localtimer thread safety issue linked to std::env::setvar).

Features

• Injects an assume_timezone member function to any PrimitiveDateTime.
• Injects a to_timezone member function to any OffsetDateTime.
• Provides a timezones::get_by_name function to get a timezone by name.
• Supports finding the closest IANA match from a windows timezone name.
• Supports obtaining system's current timezone (through the system feature).

Usage

```rust use time::macros::datetime; use time_tz::{PrimitiveDateTimeExt, OffsetDateTimeExt, timezones};

fn main() { // =========================================== // Create a new datetime in a given timezone // ===========================================

// First we have to get the source timezone:
let london = timezones::db::europe::LONDON;

// Now we can create a primitive date time and call the extension function:
let dt = datetime!(2016-10-8 17:0:0).assume_timezone_utc(london);


// ===========================
//  Convert to a new timezone
// ===========================

// First we get the target timezone:
let berlin = timezones::db::europe::BERLIN;

// Now we can convert (again by calling an extension function):
let converted = dt.to_timezone(berlin);

// ... do something with converted

} ```
