You're right but it was just to show you that it was the v2.1 upgraded with your hack (if I understood well...).
And maybe this information could give you an idea why times do not change while days after days. First shouts from first days (more than a week ago) are still on "Today" or "Yesterday" (it has change once).
I had to deactivated the hack
Note : unfortunately, there's no support there on it. They just translated it...
