Moment.js not returning correct standard time

As I am almost completing the project from FCC (https://www.freecodecamp.com/challenges/timestamp-microservice)

I am not able to figure out why when the input is in standard time, it won't output its Unix timestamp correctly.

For instance, when I type:

http://localhost:3000/January%201%201970

it will output as so:

{"unix":"28800","natural":"January 1, 1970"}

It seems like there is an offset of 8 hours (28800 seconds, but even when I apply the utcOffset(), it doesn't change.

var express = require('express');
var path = require('path')
var app = express();
var moment = require('moment')
var port = 3000;
//homepage
app.get('/', function(req, res) {
  var fileName = path.join(__dirname, 'index.html');
  res.sendFile(fileName, function (err) {
    if (err) {console.error(err)}
    console.log('This is the homepage')
  });
});

//input of the page
app.get('/:dataString', function(req, res) {
  var dataString = req.params.dataString;
  var output;
  //Using regex, checks if the dataString has only number characters
  if(/^[0-9]*$/.test(dataString)){
    output = moment(dataString, "X")
  } else{
    console.log(dataString)
    output = moment(dataString, "MMMM DD YYYY")
    console.log(output.utc().format("X"))
  }

  if (output.isValid()){
    res.json({
      unix: output.utc().format("X"),
      natural: output.utc().format("MMMM D, YYYY")
    });
  } else{
    res.json({
      unix: 'null',
      natural: 'null'
    });
  }
})

app.listen(port,function(){
  console.log("turn on. Port is: ", port)
})

In your code:

output = moment(dataString, "MMMM DD YYYY")

This is creating a moment in local time. The resulting timestamp reflects your local time zone's offset from UTC at the point in time of your dataString.

If you wanted the input to be based on UTC, then it would be:

output = moment.utc(dataString, "MMMM DD YYYY")
