你可以用unix时间戳初始化一个moment对象，然后使用format()函数来获得你想要的输出。

const yourUnixEpochTime = 1687340912000;
// Create moment object from epoch and convert to format:
const formattedTime = moment(yourUnixEpochTime).format("dddd, MMMM Do, YYYY h:mm A")

$("#time").text(formattedTime);

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.29.4/moment.min.js"></script>
<p id="time"></p>

从文档：Unix时间戳

var day = moment.unix(1318781876); //seconds
var day = moment(1318781876406); //milliseconds

// and then:

console.log(day.format('dddd MMMM Do YYYY, h:mm:ss a'));

// "Sunday October 16th 2011, 9:17:56 am"

您可以使用.format('LLLL')来满足您的需求。

let result = moment(epoch).format('LLLL');

let epoch = 1562127342123;
let result = moment(epoch).format('LLLL');
console.log(result);

可以使用moment.unix(epochTime)。

Moment JS将Unix时间转换为GMT时间。要将其转换为比协调世界时（UTC）晚5小时的EST：[momentjs]

const moment = require('moment');

console.log(moment(1580331903396).subtract(5, 'hours').format('MMMM Do, YYYY - h:mm:ss A '))
