We can get the current time in timestamp using the following method:

Date.now()

Following is the method for adding days to a date.

Date.prototype.addDays = function(days) {
    var date = new Date(this.valueOf());
    date.setDate(date.getDate() + days);
    return date;
}

var date = new Date();

console.log(date.addDays(5));

But this method does not return a unix timestamp.

How can I add days to a unix timestamp?

Is there a way to achieve this directly from the date object rather than manually using regex to parse the string? – mx_code Mar 31 '21 at 08:31
What I'm saying is that how can I add days directly to the initial timestamp? – mx_code Mar 31 '21 at 08:33
For example ```Date.now() + days``` – mx_code Mar 31 '21 at 08:33
Such that it returns a timestamp rather than a date string. – mx_code Mar 31 '21 at 08:33
This is what I want. Please try to understand the situation first. Please. – mx_code Mar 31 '21 at 08:34
Timestamp in milliseconds , like this ... 20180203073000 – mx_code Mar 31 '21 at 08:35
I didn't knew that you got confused. Normally we use timestamp for this long number and not date strings. – mx_code Mar 31 '21 at 08:36
@ChrisG Timestamp in programmer language commonly refers to unix timestamps, which count the milliseconds that have passed since January 1st, 1970. – connexo Mar 31 '21 at 08:36
Yes. Exactly. In milliseconds. That's it. How Can I achieve that? – mx_code Mar 31 '21 at 08:36
Yes Unix Timestamps. – mx_code Mar 31 '21 at 08:36
Can you help me with that? Show some code. – mx_code Mar 31 '21 at 08:37
`Date.prototype.addDays = function(days) { return this.setTime(this.getTime() + (86400000 * days)); }` – Peter Seliger Mar 31 '21 at 09:26
`const date = new Date; const time = date.addDays(5); const unix = time / 1000;` – Peter Seliger Mar 31 '21 at 09:27
