Java Data Type - 如何将“机器时间”转换为人机

import java.time.Instant;
import java.time.LocalDateTime;
import java.time.ZoneId;

public class Main {

  public static void main(String[] args) {
    // Instant is useful for generating a time stamp to represent machine time.
    Instant timestamp = Instant.now();
    // Convert "machine time" to human units
    LocalDateTime humanTime = LocalDateTime.ofInstant(timestamp, ZoneId.systemDefault());
    
    System.out.println(humanTime);
  }
}
