    var date=now.getDate();
    var month=now.getMonth()+1;
    var year=now.getYear();

    var timestr;
    timestr = year;
    timestr += ((month<10)?"0":"")+month;
    timestr += ((date<10)?"0":"")+date;

    var hours = now.getHours();
    var minutes = now.getMinutes();
    var seconds = now.getSeconds();
    var milseconds = now.getMilliseconds();
    timestr += ((hours<10)?"0":"")+hours;
    timestr += ((minutes<10)?"0":"")+minutes;
    timestr += ((seconds<10)?"0":"")+seconds;
    timestr += milseconds;
    return timestr;
