rustHow to format time in Rust

Rust provides a number of ways to format time.

The most common way is to use the chrono crate. This crate provides a number of types and functions to work with dates and times.

Example code

use chrono::{DateTime, Utc};

let now: DateTime<Utc> = Utc::now();
println!("{}", now.format("%Y-%m-%d %H:%M:%S"));

Output example

2020-09-17 11:45:00

The code above uses the chrono crate to get the current time in UTC and then formats it using the format function. The format string %Y-%m-%d %H:%M:%S specifies the format of the output.

The chrono crate also provides other types and functions to work with dates and times, such as DateTime and Duration.
