function CurentTime()
    { 
        var now = new Date();
        var year = now.getFullYear();       //年
        var month = now.getMonth() + 1;     //月
        var day = now.getDate();            //日
        var hh = now.getHours();            //时
        var mm = now.getMinutes();          //分
        var clock = year + "-";
        if(month < 10){ clock += "0";}
        clock += month + "-";
        if(day < 10){clock += "0";}
        clock += day + " ";
        if(hh < 10){clock += "0";}
        clock += hh + ":";
        if (mm < 10){clock += '0'; }
        clock += mm; 
        return(clock); 
    }
