以下方法适用于所有情况(日期之间的差异小于24小时和差异大于24小时):

// Defining start and end variables
let start = moment('04/09/2013 15:00:00', 'DD/MM/YYYY hh:mm:ss');
let end   = moment('04/09/2013 14:20:30', 'DD/MM/YYYY hh:mm:ss');

// Getting the difference: hours (h), minutes (m) and seconds (s)
let h  = end.diff(start, 'hours');
let m  = end.diff(start, 'minutes') - (60 * h);
let s  = end.diff(start, 'seconds') - (60 * 60 * h) - (60 * m);

// Formating in hh:mm:ss (appends a left zero when num < 10)
let hh = ('0' + h).slice(-2);
let mm = ('0' + m).slice(-2);
let ss = ('0' + s).slice(-2);

console.log(`${hh}:${mm}:${ss}`); // 00:39:30

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}

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"

如果你想要两个日期(startDate, endDate)之间的本地化天数:

var currentLocaleData = moment.localeData("en");
var duration = moment.duration(endDate.diff(startDate));
var nbDays = Math.floor(duration.asDays()); // complete days
var nbDaysStr = currentLocaleData.relativeTime(returnVal.days, false, "dd", false);

nbDaysStr将包含类似“3天”的内容;

例如，有关如何显示小时数或月数的信息，请参阅https://momentjs.com/docs/#/i18n/changing-locale/。

而不是

Math.floor(duration.asHours()) + moment.utc(duration.asMilliseconds()).format(":mm:ss")

最好是去做

moment.utc(total.asMilliseconds()).format("HH:mm:ss");

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
}
