-3

I want to calculate the difference between the current time and another date which I recuperate from another program. Unfortunalety, this second date is on ISO format ie. in something like that : 

date2 = "2015-07-16T16:33:39.113Z"

I want to calculate the difference between this date2 and the current time and display the difference like that " 0h 53min 10s" for example. How can I do that in node.js please?

    Did you try anything at all? Did you even try to read any basic tutorial or documentation about JS dates? Or are you simply hoping us SO community will spoon-feed you? – Amit Jul 16 '15 at 21:10

Try using moment. You get get the current time via the now() function call and manipulate dates with the framework (use diff()).

var moment = require('moment');

date2 = "2015-07-16T16:33:39.113Z"

var then = moment(date2, "YYYY-MM-DD'T'HH:mm:ss:SSSZ");
var now = moment();

var diff = moment.duration(then.diff(now));
if (diff < 0) {
    diff = Math.abs(diff);
}
var d = moment.utc(diff).format("HH:mm:ss:SSS");
console.log("Difference: " + d);

For reference, see Get the time difference between two datetimes
