    let time_jd = time.to_jd();
    println!("The Julian Date of the time is: {}", time_jd);

    // and, you can do the exact opposite, create a `Time` object
    // from a JD, MJD, GST, UTC, or ISO string:
    let time_from_jd = Time::from_jd(2459376.0);

    // so you can convert a chrono::DateTime<Utc> object to a `Time` object

    println!("{}", time.to_string(Some("mjd")));
