Rust program to convert the timestamp into readable date time

Rust | Date & Time Example: Write a program to convert the timestamp into readable date time.
Submitted by Nidhi, on November 06, 2021

Problem Solution:

In this program, we will get the current timestamp using the timestamp() method and convert the timestamp into the readable date-time format.

Add Chrono date-time external library to your project

Create your project using the below command.
```
$cargo new datetime -bin
```
Goto the project folder cd datetime and edit Cargo.toml file.
```
$datetime>nano Cargo.toml
```
Then add dependency in Cargo.toml file
```
[dependencies]
chrono = "0.4"
```
After that, build your project using the below command
```
$datetime>cargo build
```
Then execute your project after modification in src/main.rs source file.
```
$datetime>cargo run
```

Program/Source Code:

The source code to convert the timestamp into readable date-time is given below. The given program is compiled and executed on UBUNTU 18.04 successfully.

// Rust program to convert the timestamp 
// into readable date time

use chrono::prelude::*;

fn main() {
    let now = Utc::now();
    let ts: i64 = now.timestamp();
    
    println!("Current timestamp is: {}", ts);
    
    let nt = NaiveDateTime::from_timestamp(ts, 0);
    let dt: DateTime<Utc> = DateTime::from_utc(nt, Utc);
    let res = dt.format("%Y-%m-%d %H:%M:%S");
    
    println!("Date time: {}", res);
}

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 timestamp is: 1634966087
Date time: 2021-10-23 05:14:47

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::prelude::*;

In the main() function, we got the current date and time using the Utc::now() method and converted the date-time into timestamp using the timestamp() method. After that, we converted the timestamp into readable date time format and printed the result.
