Rust program to print the time in 12-hour format

Program/Source Code:

The source code to print time in 12-hour format is given below. The given program is compiled and executed on UBUNTU 18.04 successfully.

// Rust program to print the time 
// in 12 hour format

use chrono::{Datelike, Timelike, Local};

fn main() {
    let current = Local::now();
    
    let (isPm, hour) = current.hour12();
    
    println!("The current UTC time: {:02}:{:02}:{:02} {}",hour,current.minute(),current.second(),
    if isPm { "PM" } else { "AM" });
}

Output:

Local time: 2021-10-30 09:12:53.266391074 -07:00
UTC time: 2021-10-30 16:12:53.266391074 UTC
Current time in RIO(Brazil): 2021-10-30 14:12:53.266391074 -02:00

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::Utc;

In the main() function, we got the current LOCAL date-time using the Local::now() method and converted date-time in 12-hour format using the hour12() function and printed "AM", "PM" using isPm() function.
