I understand this is a popular question on the internet. But the point is that I need to do something accurately and as I'm not very familiar with working with dates, I needed to ask this question.

My problem is the following, from a timestamp I have to define certain actions. These actions are taken under the following conditions:

Prep - starts about an hour before timestamp;

Run - starts right at timestamp;

Reset - this action is taken if 15 minutes have passed after the timestamp;

Bearing in mind that the timestamp would be the following:

const timestamp = "2021-11-16T09:18:02 0000"

I had the idea to do it this way:

const time = moment(timestamp).diff(moment(), "minutes")

But to be honest I don't know how I can improve this. Can you help?
