how to convert the minutes into hours and minutes with subtracted time(subtracted time values)

Question

I want to subtract the two different 24 hours time format.

I had tried with following :

var startingTimeValue = 04:40;
var endTimeValue = 00:55;
var         


        

Answer 1

Try:

var time1 = Date.UTC(0,0,0,4,40,0);
var time2 = Date.UTC(0,0,0,0,55,0);

var subtractedValue = time1 - time2;

var timeResult = new Date(subtractedValue);

console.log(timeResult.getUTCHours() + ":" + timeResult.getUTCMinutes());

DEMO

This solution utilizes javascript built-in date. How it works:

var time1 = Date.UTC(0,0,0,4,40,0);
var time2 = Date.UTC(0,0,0,0,55,0);

time1, time2 is the number of miliseconds since 01/01/1970 00:00:00 UTC.

var subtractedValue = time1 - time2;

subtractedValue is the difference in miliseconds.

var timeResult = new Date(subtractedValue);

console.log(timeResult.getUTCHours() + ":" + timeResult.getUTCMinutes());

These lines reconstruct a date object to get hours and minutes.
