extern crate timer;
extern crate chrono;
use std::sync::mpsc::channel;
let timer = timer::Timer::new();
let (tx, rx) = channel();
let _guard = timer.schedule_with_delay(chrono::Duration::seconds(3), move || {
 tx.send(()).unwrap();
});
rx.recv().unwrap();
println!("This code has been executed after 3 seconds");
