Date and Time Errors!

My posting is so annoying! It sets the wrong Date and Time, like everytime I post someting! So I just get it now. From now on, I won't put the Date and Time on Automatic anymore cause this thing suck on doing that! And whats weird is that the Date and the Time on my Computer is correct but if I click automatic, they still set it wrong on my post! All of my recent posts have the wrong date and time, people! Its a day late from the actual date. Example: my last post's date: 30th july 10 when its supposed to be 1st july 10 okay! Adios!
