I am going through the JSON that is resulting from calling [the Stack Exchange User API][1].


I see a bunch of reputation fields.

    private Number reputation;
    private Number reputation_change_day;
    private Number reputation_change_month;
    private Number reputation_change_quarter;
    private Number reputation_change_week;
    private Number reputation_change_year;

<br>
What are all these for? Obviously, I know what the reputation is, but the others have me a bit fooled.
