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);};
