That argument localises each and every event into a time frame reference point in a language that children can be taught to comprehend. MD will not like it. IDL = International Date Line. Daylight saving at present is a political issue here in oz. I believe some nations either side of the IDL have more problems than us. Instead of a one hour difference they have one day of difference. One nation desires to move into tomorrow and so the child born on that day of change will never have a birthday to celebrate? Think about it and get back to me please expose the error. In a circle of 1000 people how many have a degree?
