I don't sure if i understand your question, but if you want format from Date to String is easy.

data = (Date.now()- data).toString();

You can use DayJs to format the date received from the server:

Day.js is a minimalist JavaScript library that parses, validates, manipulates, and displays dates and times for modern browsers with a largely Moment.js-compatible API. If you use Moment.js, you already know how to use Day.js.

const data = 1572613310373;
const formatedDate = dayjs(data).format("YYYY-MM-DD HH:mm:ss")
const output = Date.now() - data;
console.log(formatedDate);
console.log(output);

You can write a function like this You can also improve this function handling errors or invalid date

var parseDate = function (date) {
  var d = new Date(date)

  // Year
  var year = d.getFullYear()

  // Month
  var month = (d.getMonth() + 1).toString()
  month = month.length > 1 ? month : '0' + month

  // Day
  var day = d.getDay().toString()
  day = day.length > 1 ? day : '0' + day

  // hours
  var hours = d.getHours().toString()
  hours = hours.length > 1 ? hours : '0' + hours

  // minutes
  var minutes = d.getMinutes().toString()
  minutes = minutes.length > 1 ? minutes : '0' + minutes

  // seconds
  var seconds = d.getSeconds().toString()
  seconds = seconds.length > 1 ? seconds : '0' + seconds

  return year + '-' + month + '-' + day + ' ' + hours + ':' + minutes + ':' + seconds
}

var date = parseDate(1572613310373)
console.log(date) // 2019-11-05 14:01:50
