js时间戳转时间

// 假设有一个时间戳
let timestamp = 1633072800000; // 这个时间戳代表2021-10-01 00:00:00 UTC

// 创建一个新的Date对象
let date = new Date(timestamp);

// 使用toLocaleString方法转换为本地时间字符串
console.log(date.toLocaleString()); // 输出可能是"2021/10/1 上午12:00:00"，具体格式取决于浏览器和地区设置

let timestamp = 1633072800000;
let date = new Date(timestamp);

let year = date.getFullYear();
let month = ('0' + (date.getMonth() + 1)).slice(-2); // 月份是从0开始的
let day = ('0' + date.getDate()).slice(-2);
let hours = ('0' + date.getHours()).slice(-2);
let minutes = ('0' + date.getMinutes()).slice(-2);
let seconds = ('0' + date.getSeconds()).slice(-2);

let formattedDate = `${year}-${month}-${day} ${hours}:${minutes}:${seconds}`;
console.log(formattedDate); // 输出"2021-10-01 00:00:00"

// 首先需要引入moment.js库
let moment = require('moment');

let timestamp = 1633072800000;
let formattedDate = moment(timestamp).format('YYYY-MM-DD HH:mm:ss');
console.log(formattedDate); // 输出"2021-10-01 00:00:00"

// 首先需要引入date-fns库
let { format } = require('date-fns');

let timestamp = 1633072800000;
let formattedDate = format(new Date(timestamp), 'yyyy-MM-dd HH:mm:ss');
console.log(formattedDate); // 输出"2021-10-01 00:00:00"
