Moment.js gives wrong difference between 2 dates

Question

I use moment.js in my React application with the following code to find the difference between 2 unix timestamps :

import Moment from 'moment';

Moment.duration( 
    Moment(this.state.saleEndTime).diff(Moment(this.state.saleStartTime))
).humanize()

Where

• this.state.saleStartTime 1511638810 (Sat, November 25, 2017 19:40:10 GMT)
• this.state.saleEndTimeis 1516909110(Thu, 25 January 2018 19:38:30 GMT)

However, he concludes

an hour

This is obviously not correct, it should be 2 months. What have I done wrong?

Using moment v2.19.2 with node v7.9.0

---

Edit: The output should be humanize'ed, and the time difference between this.state.saleStartTimeand this.state.saleEndTimecan vary from minutes to several months ...

Answer 1

I did not know that it was a stamp unix.
You should use the method unix:

moment.duration(
  moment.unix(1516909110).diff(moment.unix(1511638810))
).humanize();

Fragment launch:

const result = moment.duration(
  moment.unix(1516909110).diff(moment.unix(1511638810))
).humanize();

const App = () => (
  <div >
    <div>{result}</div>
  </div>
);

ReactDOM.render(<App />, document.getElementById('root'));
