You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: dateutils.rs
    path of file: ./repos/chrono/tests
    
    the code of the file until where you have to start completion: #![cfg(all(unix, feature = "clock", feature = "std"))]

use chrono::{Datelike, Days, 
    
fn try_verify_against_date_command() {
    if !path::Path::new(DATE_PATH).exists() {
        eprintln!("date command {:?} not found, skipping", DATE_PATH);
        return;
    }
    assert_run_date_version();

    eprintln!(
        "Run command {:?} for every hour from 1975 to 2077, skipping some years...",
        DATE_PATH,
    );

    let mut children = vec![];
    for year in [1975, 1976, 1977, 2020, 2021, 2022, 2073, 2074, 2075, 2076, 2077].iter() {
        children.push(thread::spawn(|| {
            let mut date = NaiveDate::from_ymd_opt(*year, 1, 1).unwrap().and_time(NaiveTime::MIN);
            let end = NaiveDate::from_ymd_opt(*year + 1, 1, 1).unwrap().and_time(NaiveTime::MIN);
            while date <= end {
                verify_against_date_command_local(DATE_PATH, date);
                date += chrono::TimeDelta::try_hours(1).unwrap();
            }
        }));
    }
    for child in children {
        // Wait for the thread to finish. Returns a result.
        let _ = child.join();
    }
}
