这种方法只适用于总持续时间少于24小时的情况:

var now  = "04/09/2013 15:00:00";
var then = "04/09/2013 14:20:30";

moment.utc(moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"))).format("HH:mm:ss")

// outputs: "00:39:30"

如果你有24小时或更长的时间，用上面的方法，时间会重置为零，所以不理想。

如果你想在24小时或更长的时间内获得有效的响应，那么你必须这样做:

var now  = "04/09/2013 15:00:00";
var then = "02/09/2013 14:20:30";

var ms = moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"));
var d = moment.duration(ms);
var s = Math.floor(d.asHours()) + moment.utc(ms).format(":mm:ss");

// outputs: "48:39:30"

注意，我使用utc时间作为快捷方式。可以分别取出d.minutes()和d.seconds()，但也必须对它们进行零opad。

这是必要的，因为moment.js中目前没有格式化持续时间对象的功能。这里已提出要求。然而，有一个名为moment-duration-format的第三方插件专门用于此目的:

var now  = "04/09/2013 15:00:00";
var then = "02/09/2013 14:20:30";

var ms = moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"));
var d = moment.duration(ms);
var s = d.format("hh:mm:ss");

// outputs: "48:39:30"

这将返回最大的时间周期差异，如(4秒，2分钟，1小时，2天，3周，4个月，5年)。 我用这个来通知最近的时间。

function dateDiff(startDate, endDate) {
    let arrDate = ["seconds", "minutes", "hours", "days", "weeks", "months", "years"];
    let dateMap = arrDate.map(e => moment(endDate).diff(startDate, e));
    let index = 6 - dateMap.filter(e => e == 0).length;
    return {
        type: arrDate[index] ?? "seconds",
        value: dateMap[index] ?? 0
    };
}

例子:

dateDiff("2021-06-09 01:00:00", "2021-06-09 04:01:01")

{type: "hours", value: 3}

dateDiff("2021-06-09 01:00:00", "2021-06-12 04:01:01")

{type: "days", value: 3}

dateDiff("2021-06-09 01:00:00", "2021-06-09 01:00:10")

{type: "seconds", value: 10}

如果我们只想要hh:mm:ss，我们可以使用这样的函数:

//param: duration in milliseconds
MillisecondsToTime: function(duration) {
    var seconds = parseInt((duration/1000)%60)
        , minutes = parseInt((duration/(1000*60))%60)
        , hours = parseInt((duration/(1000*60*60))%24)
        , days  = parseInt(duration/(1000*60*60*24));

    var hoursDays = parseInt(days*24);
    hours += hoursDays;
    hours = (hours < 10) ? "0" + hours : hours;
    minutes = (minutes < 10) ? "0" + minutes : minutes;
    seconds = (seconds < 10) ? "0" + seconds : seconds;
    return hours + ":" + minutes + ":" + seconds;
}

在ES8中使用moment, now和start是moment对象。

const duration = moment.duration(now.diff(start));
const timespan = duration.get("hours").toString().padStart(2, '0') +":"+ duration.get("minutes").toString().padStart(2, '0') +":"+ duration.get("seconds").toString().padStart(2, '0');

基于日期时间的输入

    var dt1 = new Date("2019-1-8 11:19:16");
    var dt2 = new Date("2019-1-8 11:24:16");


    var diff =(dt2.getTime() - dt1.getTime()) ;
    var hours = Math.floor(diff / (1000 * 60 * 60));
    diff -= hours * (1000 * 60 * 60);
    var mins = Math.floor(diff / (1000 * 60));
    diff -= mins * (1000 * 60);


    var response = {
        status : 200,
        Hour : hours,
        Mins : mins
    }

输出

{
"status": 200,
"Hour": 0,
"Mins": 5
}

我用typescript创建了一个简单的函数

const diffDuration: moment.Duration = moment.duration(moment('2017-09-04 12:55').diff(moment('2017-09-02 13:26')));
setDiffTimeString(diffDuration);

function setDiffTimeString(diffDuration: moment.Duration) {
  const str = [];
  diffDuration.years() > 0 ? str.push(`${diffDuration.years()} year(s)`) : null;
  diffDuration.months() > 0 ? str.push(`${diffDuration.months()} month(s)`) : null;
  diffDuration.days() > 0 ? str.push(`${diffDuration.days()} day(s)`) : null;
  diffDuration.hours() > 0 ? str.push(`${diffDuration.hours()} hour(s)`) : null;
  diffDuration.minutes() > 0 ? str.push(`${diffDuration.minutes()} minute(s)`) : null;
  console.log(str.join(', '));
} 
// output: 1 day(s), 23 hour(s), 29 minute(s)
