Hello Tophe,
You might want to check your profile settings and make sure the time zone is correct for your location. Also, please keep in mind that we have two Aero-Space forums, one under Physical Models and the other under Profiles. As to your other questions, I'm not really sure. The board may be giving you overall as opposed to individual stats or counting the Admin forums (which are only visible to moderators) in the total.
I hope this helps, but if you need more assistance, feel free to drop me a personal message.
All the best,
Brian da Basher
