Try this in for Firebase V8.

 const getServerTime = () =>
firebase.firestore?.Timestamp?.now().toMillis();

Firestore have a method called toMillis(). You can use it like this. See code below:

    const docSnap = await getDoc(docRef);

    if (docSnap.exists()) {
      console.log("timestamp:", docSnap.data().timestamp.toMillis());
    } else {
      // doc.data() will be undefined in this case
      console.log("No such document!");
    }

will return something like this:

timestamp: 1647438836443

For more information, you may refer to this documentation.
