How to get the current Unix timestamp in Rust

The standard library exposes epoch seconds through `SystemTime::now().duration_since(UNIX_EPOCH)`. For ergonomic formatting most projects reach for the `chrono` crate.

`chrono::DateTime::<Utc>::from_timestamp(secs, 0)` builds a UTC instant directly from epoch seconds.

Current Unix timestamp (seconds)

use std::time::{SystemTime, UNIX_EPOCH};

let secs = SystemTime::now()
    .duration_since(UNIX_EPOCH)
    .unwrap()
    .as_secs();
println!("{}", secs); // 1,754,136,000

Convert epoch seconds → ISO 8601 (UTC)

use chrono::{DateTime, Utc};
let dt = DateTime::<Utc>::from_timestamp(1754136000, 0).unwrap();
println!("{}", dt.to_rfc3339()); // 2025-08-02T12:00:00+00:00

Example values used above: epoch seconds = 1,754,136,000 · ISO 8601 = 2025-08-02T12:00:00.000Z
