虽然这个问题是很久以前问过的，但写下这个答案希望它能帮助到一些人。

传递您想要开始计数的日期。使用momentjs的moment().fromNow():(在这里查看更多信息)

getRelativeTime(date) {
    const d = new Date(date * 1000);
    return moment(d).fromNow();
}

如果您想更改日期fromNow提供的信息，请编写自定义相对时间为时刻。

例如，在我自己的例子中，我想打印'one month ago'而不是'a month ago'(由moment(d). fromnow()提供)。在这种情况下，你可以写出下面给出的内容。

moment.updateLocale('en', {
    relativeTime: {
        future: 'in %s',
        past: '%s ago',
        s: 'a few seconds',
        ss: '%d seconds',
        m: '1 m',
        mm: '%d minutes',
        h: '1 h',
        hh: '%d hours',
        d: '1 d',
        dd: '%d days',
        M: '1 month',
        MM: '%d months',
        y: '1 y',
        yy: '%d years'
    }
});

注意:我是在Angular 6中为项目编写代码的

function timeSince(date) { var seconds = Math.floor((new Date() - date) / 1000); var interval = seconds / 31536000; if (interval > 1) { return Math.floor(interval) + " years"; } interval = seconds / 2592000; if (interval > 1) { return Math.floor(interval) + " months"; } interval = seconds / 86400; if (interval > 1) { return Math.floor(interval) + " days"; } interval = seconds / 3600; if (interval > 1) { return Math.floor(interval) + " hours"; } interval = seconds / 60; if (interval > 1) { return Math.floor(interval) + " minutes"; } return Math.floor(seconds) + " seconds"; } var aDay = 24*60*60*1000; console.log(timeSince(new Date(Date.now()-aDay))); console.log(timeSince(new Date(Date.now()-aDay*2)));

我还没有检查(虽然这并不难)，但我认为Stack Exchange站点使用jquery。Timeago插件来创建这些时间字符串。

这个插件使用起来很简单，而且很干净，还能自动更新。

下面是一个简单的例子(来自插件的主页):

First, load jQuery and the plugin: <script src="jquery.min.js" type="text/javascript"></script> <script src="jquery.timeago.js" type="text/javascript"></script> Now, let's attach it to your timestamps on DOM ready: jQuery(document).ready(function() { jQuery("abbr.timeago").timeago(); }); This will turn all abbr elements with a class of timeago and an ISO 8601 timestamp in the title: <abbr class="timeago" title="2008-07-17T09:24:17Z">July 17, 2008</abbr> into something like this: <abbr class="timeago" title="July 17, 2008">about a year ago</abbr> which yields: about a year ago. As time passes, the timestamps will automatically update.

如果你已经在使用date-fns，你可以使用内置的formatDistance(以前是distanceInWords):

const date1 = new Date(2014, 6, 2);
const date2 = new Date(2015, 0, 1);
const options = { addSuffix: true }
const result = formatDistance(date1, date2, options);
//=> '6 months ago'

我使用了可能11的旧答案，并添加了Intl。用于翻译的RelativeTimeFormat。

https://stackoverflow.com/a/73331658/673809

function timeAgo (value) { const seconds = Math.floor((new Date().getTime() - new Date(value).getTime()) / 1000) let interval = seconds / 31536000 const rtf = new Intl.RelativeTimeFormat("en", { numeric: 'auto' }) if (interval > 1) { return rtf.format(-Math.floor(interval), 'year') } interval = seconds / 2592000 if (interval > 1) { return rtf.format(-Math.floor(interval), 'month') } interval = seconds / 86400 if (interval > 1) { return rtf.format(-Math.floor(interval), 'day') } interval = seconds / 3600 if (interval > 1) { return rtf.format(-Math.floor(interval), 'hour') } interval = seconds / 60 if (interval > 1) { return rtf.format(-Math.floor(interval), 'minute') } return rtf.format(-Math.floor(interval), 'second') } console.log(timeAgo('2022-08-12 20:50:20'))

Lokely使用的一个简短版本:

const intervals = [
  { label: 'year', seconds: 31536000 },
  { label: 'month', seconds: 2592000 },
  { label: 'day', seconds: 86400 },
  { label: 'hour', seconds: 3600 },
  { label: 'minute', seconds: 60 },
  { label: 'second', seconds: 1 }
];

function timeSince(date) {
  const seconds = Math.floor((Date.now() - date.getTime()) / 1000);
  const interval = intervals.find(i => i.seconds < seconds);
  const count = Math.floor(seconds / interval.seconds);
  return `${count} ${interval.label}${count !== 1 ? 's' : ''} ago`;
}
