Example: Get time from an NTP server and sync systemtime

fn main() -> e_utils::AnyResult<()> {
    let target = "0.pool.ntp.org:123";
    let res = ntp_client::Client::new()
        .target(target)?
        .format(Some("%Y/%m/%d %H:%M:%S"))
        .request()?;
    let res_str = res.get_datetime_str().ok_or("error")?;
    println!("UTC str -> {res_str}");
    let datetime = res.get_datetime_utc().ok_or("get datetime utc")?;
    ntp_client::sync_systemtime(datetime)?;
    Ok(())
