Answer 1

If you want to add the current time as your Timestamp value in a Firestore document, you can you add it using FieldValue.serverTimestamp() as Doug mentioned, as in the following example:

import * as firebase from 'firebase';
[ . . . ]
db.collection('times').add({time: firebase.firestore.FieldValue.serverTimestamp()});

Should you want to get a specific time, you can create a new Date object and add it to your Firestore using the function toDateString() on it, as follows:

import * as firebase from 'firebase';
[ . . . ]
date = new Date('2018-11-16T09:48:51.137Z'); //sample date
this.db.collection('times').add({spec_time: this.date.toDateString()});

Answer 2

import * as firebase from 'firebase';

...


const data = {
    createdAt: firebase.default.firestore.FieldValue.serverTimestamp(),
};

This code worked for me. The important part was .default from the root firebase object.
