Just came across a crate on crates.io that recently hit v1.0.0. It’s called rkik - basically a "dig for NTP". I hadn’t seen a tool like this in Rust before.

Looks pretty handy: it can query and compare NTP servers, output JSON for monitoring, and even run continuous checks. Seems to be getting some traction in the Rust community - might be worth a look if you’re into System administration, networking or DevOps.
