你可以使用 updateLocale $自定义时刻为您的区域设置格式化相对时间的方式c $ c> 。

You can customize how moment formats relative time for you locale using updateLocale.

请注意，文档说：

如果语言环境需要对令牌进行额外处理，则可以将令牌设置为具有以下签名的函数。该函数应返回一个字符串。

If a locale requires additional processing for a token, it can set the token as a function with the following signature. The function should return a string.

function (number, withoutSuffix, key, isFuture) {
    return string;
}

在您的情况下，您可以这样做：

In your case, you can do something like this:

var m1 = moment().subtract(5, 'm');
var m2 = moment().subtract(15, 's');

console.log(m1.fromNow());
console.log(m2.fromNow());

moment.updateLocale('en', {
    relativeTime : {
        future: "in %s",
        past:   "%s ago",
        s: function (number, withoutSuffix, key, isFuture){
            return '00:' + (number<10 ? '0':'') + number + ' minutes';
        },
        m:  "01:00 minutes",
        mm: function (number, withoutSuffix, key, isFuture){
            return (number<10 ? '0':'') + number + ':00' + ' minutes';
        },
        h:  "an hour",
        hh: "%d hours",
        d:  "a day",
        dd: "%d days",
        M:  "a month",
        MM: "%d months",
        y:  "a year",
        yy: "%d years"
    }
});


console.log(m1.fromNow());
console.log(m2.fromNow());

我不确定上面的代码涵盖了你需要的所有情况，但我认为它可以是一个很好的起点。

I'm not sure that the code above covers all the case you need, but I think that it can be a good starting point.
