I wonder if this might be a browser cache issue. Can you try a different browser, or on a different computer and see if it makes any difference?
As something interesting I just learned yesterady: within the US, Hawaii and Arizona actually don’t observe DST — but Arizona is more complicated, because there are regions in Arizona that do observe DST: http://phoenix.about.com/cs/weather/qt/timezone.htm. I don’t know why DST is still a thing, in my opinion we should stop using DST 🙂
