[Firestore] Typescript error on date

[electroheadfx]

My environment

• Operating System version: macOS Monterey
• Firebase SDK version: 11.2.0
• Firebase Product: Firestore
• Node.js version: v16.17.1
• NPM version: 8.19.2

Steps to reproduce:

Just request a document with a timestamp, and get the seconds on the object:

data.entryDate.seconds

and I get this typescript error:

Any
Property 'seconds' does not exist on type 'string'.
Translation: You're trying to access seconds on an object that doesn't contain it.

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Solution: import { Timestamp } from "firebase-admin/firestore";

Maybe update the docs?

The type definitions mentioned by @galki contain the required readonly properties 'seconds' and 'nanoseconds'.
The actual runtime implementation contains the properties '_seconds' and '_nanoseconds'

I had to proxy the type since I have some areas where I validate objects at runtime and it was incorrect.
