import java.time.Duration;
import java.time.LocalDate;
import java.time.LocalDateTime;

public class MinusExample {

    public static void main(String... args) {
        Duration d = Duration.between(LocalDate.now().atStartOfDay(), LocalDateTime.now());
        System.out.println(d);

        Duration d2 = Duration.ofDays(200);
        System.out.println(d2);

        Duration d3 = d.minus(d2);
        System.out.println(d3);
    }
