When our children were little we would spend New Year's Eve with friends whose children were the same age as ours. When we arrived at their house the clocks would all be set ahead 2 hours. At ten o'clock we would ring in the 'new year' with our children, put them to bed, and then go on with our celebration.
Our kids eventually caught on and celebrated with us in real time. Now they are grown and off doing their own celebrations. I have to confess, though, that I wouldn't mind a bit if I arrived at friends' house tonight and the clocks were all set ahead two hours. For tradition, of course.
