这可能有助于：

date = new Date(1525520235000);
date.toString();

其结果是：
“2018年5月5日星期六18：37：15 GMT+0700（东南亚标准时间）”

所有get函数列表如下：https://www.w3schools.com/js/js_date_methods.asp

let x = 1525520235000;
const mydate = new Date(x);
const month = ["January", "February", "March", "April", "May", "June",
  "July", "August", "September", "October", "November", "December"
][mydate.getMonth()];
var day = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'][mydate.getDay()];

console.log('Day: ', day);

console.log('Month: ', month);

console.log('Year: ', mydate.getFullYear());

console.log("Hours: ", mydate.getHours());

console.log("Mitutes: ", mydate.getMinutes());

console.log(mydate.toString("MMMM yyyy"));

var moment = require('moment');

var dateTime = new Date(1525520235000);
var result = moment(dateTime).format('MMMM Do YYYY, h:mm:ss a');
console.log(result);

简单使用瞬间

const moment = require('moment');

var time = moment(1525520235000).format('MMMM MM YYYY h:mm:ss');

在不使用任何外部封装的情况下，使用toLocaleDateString可以获得更接近的结果，如下所示-

var date = 1525520235000;
var options = { weekday: 'short', year: 'numeric', month: 'long', day: '2-digit', hour: '2-digit', minute: '2-digit', second: '2-digit' };
var d = new Date(date);
var ds = d.toLocaleDateString("en-US", options);
console.log(ds);

其结果是：2018年5月5日，星期六，上午11：37：15
