As it turns out, I had the board default time-zone set to GMT+7 Hours, when it was actually supposed to be GMT-7 hours...
Go to your personal profiles and make sure you time-zone is correct, to get the right time-stamps on your posts.
Thanks guys.
PS if you have any suggestions for Categories, or structure, or emoticons, etc. please let me know. If you find a skin that you like for phpbb, send it to me and I'll get it installed. Basically, how things are organized and look is up to you.
