How can I format a time / duration in MomentJS so it is in Hours, Minutes and Seconds

I'm just using momentJS for the first time and I love it. However I have been using it for less than a day and I have a problem and I can't seem to find a solution, so perhaps someone here can help. In my Angular application I have a method that takes two dates as timestamps / numbers (sorry if my terminology is wrong) and this should output the difference between these two dates.

I have the following function:

   /**
   * Method that takes two timestamps and returns the number of hours between the dates
   * @param to - timestamp
   * @param from - timestamp
   */
  public calculateDuration(to: number, from: number): string {
    return moment(from).diff(moment(to), 'HHmmss');
  }

now suppose I try to call that function like so:

this.calculateDuration(156578488067,1565955844201);

I get an output of -170963523. What I am really looking for is a way for the output to be {{X}} Hours, {{Z}} Minutes and {{Y}} seconds. Using 'HHmmss' isn't correct. But playing around with the different formats listed at https://momentjscom.readthedocs.io/en/latest/moment/04-displaying/01-format/ isn't getting me anywhere. Can someone please help me understand or tell me how I can achieve the desired output using momentJS?

You could subtract directly instead of diff:

/**
 * Method that takes two timestamps and returns the number of hours between the dates
 * @param to - timestamp
 * @param from - timestamp
 */
function calculateDuration(to, from) {
  return moment(to - from).tz('America/New_York').format('HH [Hours,] mm [Minutes and] ss [seconds]');
}

console.log(calculateDuration(156578488067, 1565955844201));

Easily done with momentjs

let from = 156578488067,
    to =  1565955844201;
    
let d = moment.duration(to - from);
console.log(`${d.years()} Years ${d.months()} Months ${d.days()} Days ${d.hours()} Hours ${d.minutes()} Minutes ${d.seconds()}.${d.milliseconds()} Seconds`);
