How to get the current date and time in local and UTC in Rust example


This program prints the current date and time in the system and UTC timezone.

It uses the Chrono library to access current timestamp-related information.

Let’s create a new rust project using cargo command.

cargo new dateapp

Next, Change the directory to dateapp

cd dateapp

Add the Chrono dependency in cargo.toml file

[dependencies]
chrono = "0.4"

Now, Run the cargo build command to install all dependencies.

cargo build

Let’s write a code for the printing date in local and UTC format.

Rust Current Date and time in

Utc::now(): returns DateTime<Utc> object that contains UTC date and time Local::now(): returns DateTime<Local> object that contains System date and time

Here is an example program

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

fn main() {
    let utc: DateTime = Utc::now();
    let local: DateTime = Local::now();
    println!("Current Date and Time in UTC {:?}", utc);
    println!("Current Date and Time in System {:?}", utc);
}

Running the above code using cargo run.
