Answer 1

You need to change this line of code:

private long timestamp;

with

private Map timestamp;

And here are the corresponding public setters and getters:

public void setTimestamp(Map timestamp) {
    this.timestamp = timestamp;
}
public Map getTimestamp() {
    return timestamp;
}

Remember, that you are setting the timestamp as Map and when you are retrieving, you are retrieving it as a Long.
