What's going on with com.firebase.client.ServerValue.TIMESTAMP?

I am trying to build a chat app using Firebase on the web and build a client and Android. In my web app, I am sending the Firebase server timestamp along with the message, but I seem to be having Android issues. Using the Firebase Opensource Android chat app, I used the default Chat.java class, but when I try to send a timestamp using ServerValue.TIMESTAMP

, I get an error because I assume it will return int

, but it will Map

.

I am currently using a workaround and getting the time from the device itself, but I try to keep it consistent and reduce room for error if people in time zones use the app.

Here's my current work around the block

private void sendMessage() {
    EditText inputText = (EditText)findViewById(R.id.messageInput);
    String input = inputText.getText().toString();
    Long timestamp = System.currentTimeMillis()/1000;
    if (!input.equals("")) {
        // Create our 'model', a Chat object
        Chat chat = new Chat(name, input, timestamp, userID);
        // Create a new, auto-generated child of that chat location, and save our chat data there
        ref.push().setValue(chat);
        inputText.setText("");
    }
}

      

        
        
        
      

    

And Chat.java

public class Chat {

private String from;
private String text;
private int userID;
private Long timestamp;

// Required default constructor for Firebase object mapping
@SuppressWarnings("unused")
private Chat() { }

Chat(String from, String text, Long timestamp, int userID) {
    this.from = from;
    this.text = text;
    this.timestamp = timestamp;
    this.userID = userID;
}

public String getFrom() {
    return from;
}

public String getText() {
    return text;
}

public Long getTimestamp() {
    return timestamp;
}

public int getuserID() {
    return userID;
}

      

        
        
        
      

    

}
