Okay, so the main thing is that your computer and SWTOR.com account settings should match. Please set these accordingly and also delete your browsers cache and cookies to be sure nothing causes an issue there.
Let us know if the issue persists.
My computer has current italian time i don't want the forum to match my computer, i want it to match italian time...
BTW I don't understand your phrase "set these accordingly": my timezone is CEST (GMT +1 that, considering daylight saving time, becomes GMT+2), have i to set GMT+2 as it was before (read my first post) when the forum time was 2 hours behind or set GMT+1 as you asked me in your reply?
