I cant get the right date from mongodb in android kotlin

I try to fetch data her from mongoDb everything works except the date. It just shows the current date on the device. This is for android kotlin.

class TransactionObject : RealmObject {

    @PrimaryKey
    var _id: ObjectId = ObjectId.invoke()
    var amount: Double = 0.0
    var category: CategoryObject? = null
    var currency: String? = null
    var date: Date = Date()
    var descr: String = ""
    var ownerId: String = ""
}
{
  "properties": {
    "_id": {
      "bsonType": "objectId"
    },
    "amount": {
      "bsonType": "double"
    },
    "category": {
      "bsonType": "objectId"
    },
    "currency": {
      "bsonType": "string"
    },
    "date": {
      "bsonType": "date"
    },
    "descr": {
      "bsonType": "string"
    },
    "merchant": {
      "bsonType": "objectId"
    },
    "ownerId": {
      "bsonType": "string"
    },
    "type": {
      "bsonType": "string"
    }
  },
  "required": [
    "_id",
    "amount",
    "date",
    "descr",
