This is the same way through out the Middle East, one question that was asked as we were flying in to Abu Dhabi, "How long should I set my watch back?" the answer from the stewardess was " about 800yrs". But if you get chance to read this book its called Princess and its a true story of how Women are treated in an Islamic household. Don't know if the Libary would have it but if not they have it at Amazon.
