rsntp

An RFC 4330 compliant Simple Network Time Protocol (SNTP) client library for Rust.

rsntp provides both a synchronous (blocking) and an (optional) asynchronous API which allows synchronization with SNTPv4 servers. Time and date handling is based on the chrono crate.

Usage

Add this to your Cargo.toml:

toml [dependencies] rsntp = "0.3.1"

Obtain the current local time with the blocking API:

```rust use rsntp::SntpClient; use chrono::{DateTime, Local};

let client = SntpClient::new("pool.ntp.org").unwrap(); let result = client.synchronize().unwrap();

let localtime: DateTime = DateTime::from(result.datetime()); println!("Current time is: {}", localtime); ```

And a function which uses the asynchronous API to obtain local time:

```rust use rsntp::AsyncSntpClient; use chrono::{DateTime, Local};

async fn local_time() -> DateTime { let client = AsyncSntpClient::new("pool.ntp.org"); let result = client.synchronize().await.unwrap();

DateTime::from(result.datetime()) } ```

Disabling asynchronous API

The asynchronous API is compiled in by default but you can optionally disable it. This removes dependency to tokio which reduces crate dependencies significantly.

toml [dependencies] rsntp = { version = "0.3.1", default-features = false }
