Я создаю простую функцию с машинописным текстом

const diffDuration: moment.Duration = moment.duration(moment('2017-09-04 12:55').diff(moment('2017-09-02 13:26')));
setDiffTimeString(diffDuration);

function setDiffTimeString(diffDuration: moment.Duration) {
  const str = [];
  diffDuration.years() > 0 ? str.push(`${diffDuration.years()} year(s)`) : null;
  diffDuration.months() > 0 ? str.push(`${diffDuration.months()} month(s)`) : null;
  diffDuration.days() > 0 ? str.push(`${diffDuration.days()} day(s)`) : null;
  diffDuration.hours() > 0 ? str.push(`${diffDuration.hours()} hour(s)`) : null;
  diffDuration.minutes() > 0 ? str.push(`${diffDuration.minutes()} minute(s)`) : null;
  console.log(str.join(', '));
} 
// output: 1 day(s), 23 hour(s), 29 minute(s)
