[FireStore] How to decode Timestamp in Multiplatform Code (Android/iOS)

Given

data class Article(
    val title: String = "",
    val subTitle: String = "",
    val image: String = "",
    val date: Double = 0.0,
    val content: String = ""
)

Firebase.firestore.collection("articles")
            .get()
            .documents
            .map { doc ->
                Article(
                    doc.get("title"),
                    doc.get("subTitle"),
                    doc.get("image"),
                    doc.get("date"),
                    doc.get("content")
                )
            }

When

date is type timestamp in Firestore.

Then

How do we decode this type in commonMain for example? I have tried setting Article.date to String and Double and both crash.

 kotlinx.serialization.SerializationException: Expected Timestamp(seconds=1606944088, nanoseconds=0) to be double

Does the SDK provide any method to help with decoding this automatically?

What about encoding it ? i.e. adding a date in the where clause Query.where(“updatedDate”, greaterThan = what_to_place_here)
