Java修改机器系统时间实战

有些自动化测试过程中需要修改系统时间，代码如下 

package ***.aw;

import com.autotestframe.core.basic.ActionWord;

import java.util.Date;

public class AWChangeTime extends ActionWord {
    private int minueTimes;
    private String pastOrFuture;
    private String host ;
    private int port = 22;
    private String user ;
    private String passwd;
    @Override
    public boolean compareExpectAndActual()  {
        long nowTime=System.currentTimeMillis();
        long setTime=0;

        switch (pastOrFuture) {
            case "Past":
                setTime =nowTime - minueTimes*60*1000;
                break;
            case "Future":
                setTime =nowTime + minueTimes*60*1000;
                break;
            default:
                logger.info("请选择设置时间为过去还是未来，当前选择错误：{}。",pastOrFuture);
                break;
        }
        String dateTime=stampToDate(setTime);
        if(0==setTime){
            logger.info("修改时间有误setTime：{}.",setTime);
        }else if(host!=null && user!=null && passwd!=null && !host.equals("")&& !user.equals("")&& !passwd.equals(""))
        {     //host不为null则设置host机器的系统时间
            SshCfg cfg = new SshCfg();
            cfg.setHost(host);
            cfg.setUser(user);
