Get time difference in hh: mm between two dates using moment
I have a problem getting the time difference between two timestamps (epoch format).
I used moment().format("L LT")
to convert it to my desired time format (t21>), but now the problem is that I want the time difference inhh:mm
PS: it could be more than 24 hours.
What I have tried:
let timeDiffms,duration,timedifference,
start moment(startTimeStampInMS).format("L LT"),
end = moment(endTimeStampInMS).format("L LT");
timeDiffms = moment(end, "MM/DD/YYYY HH:mm").diff(moment(start, "MM/DD/YYYY HH:mm"));
duration = moment.duration(timeDiffms);
timedifference = Math.floor(duration.asHours()) +":"+duration.minutes(); // result
//output I am getting
// start = "03/20/2017 3:11 PM" end="03/21/2017 9:45 AM" timedifference = "30:24", (incorrect)
// start = "03/20/2017 10:07 AM" end="03/23/2017 11:24 AM" timedifference = "73:17" (correct)
// start = "03/20/2017 3:11 PM" end="03/23/2017 11:31 AM" timedifference = "80:20" (incorrect) strange
I don't know what's going on here.

Based on the previous answer, I was able to work around this logic and get the correct solution for my question.
let start moment(startTimeStampInMS),
end = moment(endTimeStampInMS);
let timediffms = end-start; // difference in ms
let duration = moment.duration(timediffms);
// _data should not be used because it is an internal property and can
//change anytime without any warning
//let hours = duration._data.days*24 + duration._data.hours;
//let min = duration._data.minutes;
let hours = duration.days()*24+ duration.hours();
let min = duration.minutes();
timeDifference = hours +":"+ min; // Answer

In your current solution, you format the object as a string and then parse the string until you get it diff
. You don't need to follow this two-step process, you can do the following to get the duration:
start moment(startTimeStampInMS),
end = moment(endTimeStampInMS).format("L LT");
timeDiffms = end.diff(start);
duration = moment.duration(timeDiffms);
Or, since your input is in milliseconds:
moment.duration(endTimeStampInMS - startTimeStampInMS);
To get duration
in the format HH:mm
, you can use the duration-format module , which adds a format
method to the duration object.
Here's a working example:
// Example milliseconds input
let startTimeStampInMS = 1490019060000;
let endTimeStampInMS = 1490085900000;
// Build moment duration object
let duration = moment.duration(endTimeStampInMS - startTimeStampInMS);
// Format duration in HH:mm format
console.log( duration.format('HH:mm', {trim: false}));
