Discord Node.js | Adding time onto a timestamp in an embed (v12)

Question

I had a question, so I know to add a timestamp to a New Discord.MessageEmbed() you would use .setTimestamp(), however, I was wondering how I would go about adding x amount of time to that timestamp, i.e. if my args[1] was "12hr" (12 hours), how would I make the timestamp display a time 12 hours ahead of whoever is viewing the message?

Basically, I'm creating a giveaway-type bot, for personal use, and I'd like the footer to display the end date.

Let's say you have let timeAdded = 12h;. There is ms package for translating that to time in milliseconds.

Also, note that .setTimestamp() method has optional parameter timestamp, that defaults to Date.now().

If you connect all this information, you'll get:

const ms = require('ms');
let timeAdded = '12h';
const NewEmbed = new Discord.MessageEmbed()
.setTimestamp(Date.now() + ms(timeAdded));

And that's it! Of course timeAdded will have to come from your args string, or in some way be fetched from the message, but you get the idea.
