Angular Firestore Sorting documents by timestamp value

I have a question which I'm hoping someone could answer as it's been two days I'm trying to sort it with absolutely no luck.

I have a collection of documents, so far so good..

Each of this documents has a field "preferred_time" that has a timestamp as a value.

Is it possible to sort the documents inside the collection using this value as reference?

I tried:

 return this.afs.collection('viewings', ref => 
    ref.orderBy('preferred_time')
    );

but it doesn't seem to work with timestamps field types.

Please help!!

Thanks, M.

You can sort your preferred_time on desc or asc. Read more here: https://firebase.google.com/docs/firestore/query-data/order-limit-data

 return this.afs.collection('viewings', ref => 
ref.orderBy('preferred_time','desc'))
);
