为什么创建出来的文件的lastModified()都一样?

Java code

import java.io.File;import java.io.IOException;public class Test {    /**     * @param args     * @throws IOException     */    public static void main(String[] args) throws IOException {        File file = new File("aaa.txt");        file.createNewFile();        try {            Thread.sleep(1000);        } catch (InterruptedException e) {            e.printStackTrace();        }        File file1 = new File("aaa1.txt");        file1.createNewFile();        // file1.setLastModified(file.lastModified() + 1);        System.out.println(file.lastModified());        System.out.println(file1.lastModified());    }}
