This script should do what you require, we record the time once we start the app, then reset every timer interval.

const port = 8080;
const app = express();
const timerDurationSeconds = 10 * 60;

let timerStart = new Date().getTime();

/* Reset the timer on each interval. */
setInterval(() => { 
    console.log("Resetting timer...");
    timerStart = new Date().getTime();
}, timerDurationSeconds * 1000);

app.get('/timer', function(req, res) {
    let elapsedSeconds = (new Date().getTime() - timerStart) / 1000;
    let minutes = Math.floor(elapsedSeconds / 60 ).toFixed(0).padStart(2, "0");
    let seconds = Math.round(elapsedSeconds % 60).toFixed(0).padStart(2, "0");
    res.send( `${minutes}:${seconds}`);
})

app.listen(port);
console.log(`Serving at http://localhost:${port}`);

Calling 

curl http://localhost:8080/timer

should show the response.

This will look like (for example): 

01:22
