Yes, it is a real difference that bit me a few times when I forgot about the 1 week difference. The worst is that this week of difference is present or not depending on the years. The second nightmare is the week iof difference in daylight saving time (in Europe we switch a week earlier or later vs the US, I do not remember anymore)
