Well, I think 59N and 17E is what your machine uses, hence the problem:
Your longitude is 17.643E - more then halfway closer to 18E - so your 
machine 'wakes up' one hour later than you do? Or is it the other way 
around?

Otherwise, I am out of ideas other than donning sunglasses at sunrise... :-;
