修改Windows和linux系统时间

1、修改本机Windows的系统时间，Java代码实现：

import java.io.IOException;

import java.text.SimpleDateFormat;

import java.util.Date;

public class ChangeWindowsDate {

    /**

     * @param args

     * @throws IOException

     */

    public static void main(String[] args) {

        try {

            Runtime.getRuntime().exec("cmd /c date 2013-11-08") ;

            Runtime.getRuntime().exec("cmd /c time 18:10:00") ;

        } catch (IOException e) {

            e.printStackTrace() ;

        }

        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss") ;

        Date date = new Date() ;

        System.out.println(sdf.format(date));

    }

}

2、修改远程Linux Server的系统时间，Java代码实现：

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStream;

import java.io.InputStreamReader;

import ch.ethz.ssh2.Connection;

import ch.ethz.ssh2.Session;

import ch.ethz.ssh2.StreamGobbler;

public class ChangeLinuxDate {

    /**

     * @param args

     */

    public static void main(String[] args) {

        String host_ip1 = "192.168.1.118" ;

        int port = 22 ;

        String username = "root" ;

        String password = "123456" ;

        String cmd = "date -s '2013-08-04 23:00:00'" ;

        Connection conn1 = new Connection(host_ip1, port) ;

        Session session1 = null ;

        try {

            conn1.connect() ;

            boolean isconn = conn1.authenticateWithPassword(username, password) ;

            if(!isconn){

                System.out.println("用户名称或者是密码不正确");

            }else{

                System.out.println(host_ip1 + ":" + "已经连接OK");

                session1 = conn1.openSession() ;

                session1.execCommand(cmd) ;

                InputStream is = new StreamGobbler(session1.getStdout());

                BufferedReader brs = new BufferedReader(new InputStreamReader(is));

                while(true){

                    String line = brs.readLine();

                    if(line==null){

                        break;

                    }

                    System.out.println(line);

                }

                is.close() ;

                brs.close() ;

                session1.close() ;

                conn1.close() ;

            }

        } catch (IOException e) {

            e.printStackTrace() ;

        }

    }

}
