Description of problem:

The SDK documentation[1] and the code comments[2] state that the connection.timeout parameter is in seconds.

However, at least on the latest versions, it seems to be in milliseconds. Setting it to 30000 results in 30s timeout:

~~~
import static org.ovirt.engine.sdk4.ConnectionBuilder.connection;

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import java.util.List;

import org.ovirt.engine.sdk4.Connection;
import org.ovirt.engine.sdk4.services.SystemService;
import org.ovirt.engine.sdk4.types.Property;
import org.ovirt.engine.sdk4.types.SchedulingPolicy;

public class Sample {
    public static void main(String[] args) throws Exception {
        DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy/MM/dd HH:mm:ss");
        LocalDateTime now = LocalDateTime.now();
        System.out.println("Attempting connection at "+dtf.format(now));
        Connection connection = null;
        try {
        connection = connection()
                    .url("https://engine.kvm/ovirt-engine/api")
                    .user("admin@internal")
                    .password("redhat")
                    .timeout(30000)        <------------------------
                    .insecure(true)
                    .build();
        connection.systemService().get().send();
        }catch(Exception e) {
                e.printStackTrace();
        }
        now = LocalDateTime.now();
        System.out.println("Connection method returned at "+dtf.format(now)+"");

        connection.close();
    }
}
~~~

Output:
