Java Data Type - 如何获得两个即时的持续时间

import java.time.Duration;
import java.time.Instant;

public class Main {
  public static void main(String[] args) {
    Instant firstInstant = Instant.ofEpochSecond(1294881180); 
    Instant secondInstant = Instant.ofEpochSecond(1294708260); 

    Duration between = Duration.between(firstInstant, secondInstant);

    System.out.println(between);
  }
}
