Ok, i go nuts...  
I cannot get it working with all examples that i can find on google so i hope some one here knows the magic...

I have the date and time with the function below, but i want to add 7 minutes to it, and if it goes above 60 minutes it needs to go to the next hour and so on.

```auto
    var currentdate = new Date() + 60000; 
    var t2 = "Datum : " + new Date().today() + " - " + new Date().timeNow();

```

But i have the idea that timeNow makes it more difficult because i don't see that in all the examples

Thanks for your help 😉

Its fun when you can't quite get things working.

Quick question: What is the `+ 60000` at the end of the first line?

(7 minutes isn't 60000 (anything))

What are you using to do this trick? Just _maths_ or are you using other nodes?

This is a flow I just made (nothing against @knolleary) and though it uses the `moment` node, is ok.

Nick, sorry, but I am missing how that works.

I see `now` no problems and I can see how you get the `then` as it is pretty much what I did in my `function` node.

But the last line.....

I don't get it. Would you mind explaining how it works?

When you want a new Date object, you do:

```auto
var d = new Date()

```

This gives you a Date object that represents the time at the moment you called it.

However the Date constructor function can also be passed an argument. If that argument is a number, it is treated as a value of milliseconds since epoch (Jan 1st, 1970 for historic reasons) and the resulting Date object will represent _that_ point in time instead of now.

Yeah, ok.... But.... Sorry.

If you load my flow, it works. No offence.

I saw yours and am not sure what the _end user variable_ is.

Is it _thenDate_?

I tried that in my flow and it doesn't add the `7 minutes`.

This is a screen show of the flow (first)  
I'm saving electrons with the dark theme. 😉

It isn't I want to hi-jack the thread, but I am not getting why it isn't adding the 7 minutes when I put in your but of code rather than mine.

The outputs are "now"  
the second `debug` is my code  
the third `debug` is with your code.

</div>

The **`Date.now()`** method returns the number of milliseconds elapsed since January 1, 1970 00:00:00 UTC.

So if you add `60*1000` you add 1 minute.

If you add `7*60*1000*` you add 7 mins.

The rest is as nick said

Edit corrected math

I'm not in a position to import a flow to look at it.

The code I provided wasn't a full and complete Function node example. It just showed the principle of how to get a Date object that represents 7 mins from now.

I got the maths wrong.

`60*1000` is 1 minute in millisecs

So 7 mins is `7*60*1000`.

No worries.

I basically did what you did. I added it to the _now_ timestamp. (From the `inject` node)  
I added 420,000 (7 minutes) and put it through the `moment` node to make it _human readable_.

I see a `+ 7 minute` addition to the _now_ time - and it is/was good that it was 59 minutes when posting as it shows the _carry over_ working - and I see the expected (correct) future time.

Using your code and using the `then` variable from your code, I send that into the `moment` node and get the time now, not in 7 minutes time.

No problems. I'm stupid. I get that. I was just not understanding how to use the last line in the code you posted and which is the one you ultimately use.

Yes, I know I have kind of contradicted myself in the names I use/d in the code.

Originally I thought it is/was: `thenDate` and used `then` in the code. But I'm guessing `thenDate` is _formatted_? and `then` is just the time stamp of the future time.

So long as @RogierQ gets it.

That's ok about the maths being wrong, but if you look at the screen shot, you can see the _time_ isn't changed from the original input value.

Again, I probably also made a mistake in what I did in the function node, but for the sake of clarity this is what I have in the second `function` node:

Ah! Yeah. Ok. The hours went crazy. I wasn't looking that much at that part.

My apologies.  
(It happens)

I see this still hasn't been _resolved_ (_solved_)

Thinking from another _angle_:

You want something to happen in _7 minutes time_. (Nominal value)

There is an event to trigger this whole thing happening.  
Why not just use a `delay` node?

Set it for 7 minutes delay.

The signal is received.  
It is delayed 7 minutes and sends on the signal.  
This can then be used to trigger the things you want to be done being done.

Just another way of looking at the question.
