js 时间戳转换成正确的时间格式（本地时间早八小时问题解决）

 js
$.renderDateTime = function (jsondate) {
    var timeStamp = parseInt(jsondate.replace(/\D/igm, ""));
    timeStamp = timeStamp - 8 * 60 * 60 * 1000; //（本地时间）东八区减去8小时
    var date = new Date(timeStamp);

    var year = date.getFullYear();
    var month = date.getMonth() + 1;
    var day = date.getDate();
    var hour = date.getHours();
    var minute = date.getMinutes();
    var second = date.getSeconds();
    return year
        + "-" + (month < 10 ? "0" + month : month)
        + "-" + (day < 10 ? "0" + day : day)
        + " " + (hour < 10 ? "0" + hour : hour)
        + ":" + (minute < 10 ? "0" + minute : minute)
        + ":" + (second < 10 ? "0" + second : second);
};
