这一个有一个解决方案：在js中将unixtime stamp转换为tim

var a = new Date(UNIX_timestamp*1000);
var hour = a.getUTCHours();
var min = a.getUTCMinutes();
var sec = a.getUTCSeconds();

time = Math.round(((new Date()).getTime()-Date.UTC(1970,0,1))/1000);

下面是一个生成时间戳的简单函数，格式为：mm/dd/yy hh:mi:ss

function getTimeStamp() {
    var now = new Date();
    return ((now.getMonth() + 1) + '/' +
            (now.getDate()) + '/' +
             now.getFullYear() + " " +
             now.getHours() + ':' +
             ((now.getMinutes() < 10)
                 ? ("0" + now.getMinutes())
                 : (now.getMinutes())) + ':' +
             ((now.getSeconds() < 10)
                 ? ("0" + now.getSeconds())
                 : (now.getSeconds())));
}

Moment.js可以消除处理Javascript Dates时的许多痛苦。

参见：http://momentjs.com/docs/#/displaying/unix-时间戳/

moment().unix();

我还没见过

Math.floor(Date.now() / 1000); // current time in seconds

另一个我还没看到的是

var _ = require('lodash'); // from here https://lodash.com/docs#now
_.now();
