How do I change my time zone?
If the time stamps you see on Facebook are incorrect, your computer’s time settings are probably wrong. Facebook uses your computer’s time settings, so please make sure this information is correct. Once you have adjusted these settings, log out of Facebook and then log back in. Your Facebook time stamps should be adjusted accordingly.

Klicka på klockan och välj "Change date and time settings" för att kontrollera så att tidszonen är satt till "(UTC+01:00) Amsterdam, Berlin, Bern, Rome, Stockholm, Vienna".
