【AE脚本】怎么获取系统时间？

function getTime(){
    var myDate = new Date();
    var thisYear=myDate.getFullYear() ;//获取当前年份(2位)
    var thisMonth=myDate.getMonth();
    var thisDate=myDate.getDate(); //获取当前日(1-31)
    var thisHours=myDate.getHours(); //获取当前小时数(0-23)
    var thisMinutes=myDate.getMinutes(); //获取当前分钟数(0-59)
    var thisSeconds=myDate.getSeconds(); //获取当前秒数(0-59)
    var thisTime=thisYear+"/"+(parseInt(thisMonth)+1)+"/"+thisDate+"/"+thisHours+":"+thisMinutes;//+":"+thisSeconds;
    return thisTime;
}
