MomentJS add function not adding time - node.js

Question

I've checked all the other forums asked on the forums here tried the clone method doesn't seem to work either. What I'm trying to do is make a key claim system and it'll get the current date and add whatever number the key has assigned to it for example key is assigned 10 days it'll add 10 days to the date. Yet it doesn't add time.
This is what it returns to console when trying to add 10 days

Here's my code
let userDB = await userSchema.find({ UserID: id });
let keysDB = await keysSchema.find({ Key: key });
var todayTime = moment(new Date());
let todayCurTime = todayTime.clone();
userDB = new userSchema({
Name: name,
Discrim: discrim,
UserID: id,
Time: todayCurTime.add(keysDB.Time, 'days')
})
console.log(`Updated time ${todayCurTime.add(keysDB.Time, 'days')}`)
await userDB.save().catch(err => console.log(err));

Moment.add() mutates the original moment rather than returning an updated moment object (source from docs). It appears that it does return a moment, but specifically the value that the moment had before it was updated. This is a rather odd way to implement things, to say the least, so it's not surprising that it tripped you up.
You need to do your time manipulation before you read from the value. The following should work:
let userDB = await userSchema.find({ UserID: id });
let keysDB = await keysSchema.find({ Key: key });
// You don't need to pass a Date() object if you just want the current date & time
const todayTime = moment();
const todayCurTime = todayTime.clone();
todayCurTime.add(keysDB.Time, 'days')
userDB = new userSchema({
Name: name,
Discrim: discrim,
UserID: id,
Time: todayCurTime
})
console.log(`Updated time ${todayCurTime}`)
await userDB.save().catch(err => console.log(err));
