Built in moment can do this in a change node.

Alternatively in a function node with

```auto

const d = new Date(msg.payload)
msg.payload = {}

// Get UTC ms since epoch
msg.payload.ts= d.valueOf()

// Get iso time
msg.payload.iso = d.toISOString()

return msg

```

_(Assumes the time to convert is in msg.payload)_

Ref: [Date.prototype.toISOString() - JavaScript | MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)

I assume you mean an iso string because I associate `timestamp` with the numeric Epoch in JavaScript.
