Firebase ServerValue.timestamp() continuously changes in firebase database - ios

Question

I am Trying to add an instance of ServerValue.timestamp() into my firebase database, when i run the app , the time stamps continuously increase here is the code, im not sure how to stop the timestamp from increasing in firebase
here is my custom class and my tableview class
class Story
{
var text: String = ""
var timestamp: String = ""
let ref: DatabaseReference!
init(text: String) {
self.text = text
ref = Database.database().reference().child("People").child("HomeFeed").child("Posts").childByAutoId()
}
init(snapshot: DataSnapshot)
{
ref = snapshot.ref
if let value = snapshot.value as? [String : Any] {
text = value["Post"] as! String
ref.updateChildValues(["timestamp":ServerValue.timestamp()])
let id = ref.key
Database.database().reference().child("People").child("HomeFeed").child("Posts").child("\(id)").child("timestamp").observeSingleEvent(of: .value) { (snapshot) in
let dope = snapshot.value as! Double
let x = dope / 1000
let date = NSDate(timeIntervalSince1970: x)
let formatter = DateFormatter()
formatter.dateStyle = .long
formatter.timeStyle = .medium
DispatchQueue.main.async {
self.timestamp = formatter.string(from: date as Date)
self.timestamp = "\(value["timestamp"])"
}
}
}
}
func save() {
ref.setValue(toDictionary())
}
func toDictionary() -> [String : Any]
{
return [
"Post" : text,
"timestamp" : timestamp
]
}
}
here is the tableview class
class TableViewController: UIViewController,UITableViewDataSource, UITableViewDelegate {
let databaseRef = Database.database().reference()
#IBOutlet weak var tableView: UITableView!
