There is no patch yet because no one has figured out what’s causing it in the cases described here.
Anyone who is experiencing the problem: Do you have access to your database? Look in a BP table (wp_bp_activity, let’s say). The timestamps there should be in UTC. So if you’re in Denver, they should read 7 hours earlier than your local time. Is that the case, or are you seeing a different offset? (Or none at all?)
