How to Work with Time Zones in Rust

Use the chrono crate to handle time zones by parsing timestamps into DateTime objects and converting them between Utc and Local or specific TimeZone instances.

use chrono::{DateTime, Utc, Local, TimeZone};

fn main() {
    let utc_now: DateTime<Utc> = Utc::now();
    let local_now: DateTime<Local> = Local::now();
    let converted = utc_now.with_timezone(&Local);
    println!("UTC: {}", utc_now);
    println!("Local: {}", local_now);
    println!("Converted: {}", converted);
}

Add chrono = "0.4" to your Cargo.toml dependencies.

Time zones are like different clocks around the world showing different times for the same moment. You use a library called chrono to keep track of the exact moment in a universal way (UTC) and then translate it to whatever local time your users need. This prevents confusion when your app runs on servers in different countries.
