calculate difference between two times in moment js [duplicate]

问题

I'm writing a service in node js. I have used moment js for time related solutions. I want to calculate the time difference between two times. Here is my snippet and it's not giving me the desired output :

var now = moment('11:08:30',"H:mm:ss");
var prev = moment('11:07:30', "H:mm:ss");
var result = moment(now.diff(prev)).format("H:mm:ss");
console.log(result);

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.4.0/moment.min.js"></script>

As per my understanding, I think the difference between 11:08:30 and 11:07:30 should come out as 00:01:00 but instead the output is coming as 5:31:00. I don't understand why this is happening. How do I fix it so that the output is 00:01:00 i.e 1 minute ?

This is a working example,

var now = moment('11:08:30',"H:mm:ss");
var prev = moment('11:07:30', "H:mm:ss");

 function dateDifference(startDate, endDate){
        return moment(startDate).diff(moment(endDate), 'seconds');
    }
    console.log(this.dateDifference(now,prev))

The supported measurements are years, months, weeks, days, hours, minutes, and seconds. For ease of development, the singular forms are supported as of 2.0.0. Units of measurement other than milliseconds are available in version 1.1.1.

Now, once u get answer in seconds, then please follow this link to convert seconds into your desired format 'h:mm:ss'

format seconds into 'hh:mm:ss'
