android - How do I cast FieldValue.serverTimestamp() to Kotlin/Java Date Class

Question

I want to save the date that a post was created in Firestore but I do not want to use the System time. Rather I want to use the server timestamp for accuracy sake. So I am using FieldValue.serverTimestamp() to get the server timestamp but the data type of my variable that holds this is Date. So How can I cast FieldValue.serverTimestamp() to Date?

Below is how my data class looks

data class MyModel( var timeStamp: Date,
    constructor(): this(Calendar.getInstance().time, "")
}

PS: When I declare the timestamp as FieldValue in the data class, I get the error below:

java.lang.RuntimeException: No properties to serialize found on class com.google.firebase.firestore.FieldValue
