public class Demo {
	public static void main(String[] args) {
		Instant time1 = Instant.now();
		Instant time2 = time1.plus(5, ChronoUnit.HOURS).plus(50, ChronoUnit.SECONDS);
		Duration duration = Duration.ofSeconds(13);
		Instant i = time1.plus(duration);
		System.out.println("Milliseconds between two time instants = "+ChronoUnit.MILLIS.between(time1, time2));
