Rust program to get the current date and time based on local time zone

Rust | Date & Time Example: Write a program to get the current date and time based on local time zone.
Submitted by Nidhi, on November 06, 2021

Problem Solution:

In this program, we will get the current date and time according to the local time zone using the now() function of Local and print the result.

Add Chrono date-time external library to your project

1. Create your project using the below command.
   

   $cargo new datetime -bin

2. Goto the project folder cd datetime and edit Cargo.toml file.
   

   $datetime>nano Cargo.toml

3. Then add dependency in Cargo.toml file
   

   [dependencies]
   chrono = "0.4"

4. After that, build your project using the below command
   

   $datetime>cargo build

5. Then execute your project after modification in src/main.rs source file.
   

   $datetime>cargo run

Program/Source Code:

The source code to get the current date and time based on the local time zone is given below. The given program is compiled and executed on UBUNTU 18.04 successfully.

// Rust program to get the current date and time 
// based on local time zone

use chrono::Local;

fn main() {
    let now = Local::now();
    println!("Current DateTime: {}", now);
}

Output:

$datetime> cargo run
   Compiling datetime v0.1.0 (/home/arvind/Desktop/rust/datetime)
    Finished dev [unoptimized + debuginfo] target(s) in 0.29s
     Running `target/debug/datetime`

Current DateTime: 2021-10-22 21:55:23.525405688 -07:00

Explanation:

In the above program, we imported the "Chrono" library to our project for performing date and time operations. We imported the Chrono library using the below line:

use chrono::Local;

In the main() function, we got the current date and time according to the local time zone using Local::now() method and printed the result.
