Logs aren't working ... No records found

How do i get my logs working? I can see (from the Dashboard) Alerts, but it does not show all of the changes. And the times are wrong. For example: I locked the front door at 8:30 am this morning, but the Alerts states that the Front door (last state change) was 23 hours ago. This is wrong;8:30 am was 5 hours ago. Help?
