endTime.subtract(duration);

Should do the trick ,here is the docs if you want to dig deeper docs

Edit:

const endTime = moment(); //now time
const duration = request.input('duration') //duration in miliseconds
let startTime = endTime.subtract(duration,'ms')


const endTime = moment(); //now time
const duration = 600000; //hardcoded 10 mins //duration in miliseconds
console.log(endTime)
let startTime = endTime.subtract(duration, 'ms')
console.log(startTime)

You can use endTime.subtract(duration, 'ms'). But for that endTime has to be a moment object. So format the answer later.

const endTime = moment();
const duration = request.input('duration')
let startTime = endTime.subtract(duration,'ms').format('HH:mm:ss')
