Certain countries observe daylight savings time where the clocks go backwards or forwards depending on the time of the year, the clocks went back an hour recently and normally in your profile when you have "Automatically detect DST Settings" set, it should automatically change the server time to the correct time according to your timezone, it isn't happening, the server time for me is still an hour ahead despite having the "Automatically detect DST settings" selected and choosing the correct timezone.
