ReferenceError: Timestamp Is Not Defined

I am trying to convert Firebase TimeStamp into JavaScript date.

I referred this link to convert Javascript object to Javascript date, https://firebase.google.com/docs/reference/js/firebase.firestore.Timestamp

Firestore timestamp (From API):

"time": {
       "_seconds": 1563620755,
        "_nanoseconds": 688000000
 }

Before saving time into cloud firestore I've to convert it to JavaScript Date().

So I used below code to convert object into Date.

let data = request.body
let tiemStamp = new Timestamp(data.time._seconds,data.time._nanoseconds)

But I got below error,

ReferenceError: Timestamp is not defined

How do to solve it? Thanks!

As Timestamp is under firebase.firestore namespace (or in Javascripts case object), you might want to use it as follows:

let tiemStamp = new firebase.firestore.Timestamp(data.time._seconds,data.time._nanoseconds)

console.log(new firebase.firestore.Timestamp());
