While you are mostly correct, be aware there is an issue with the clock only during the month of February. When left in GPS it will "sometimes" display erratic symbols and mis-information. There have been emails and alert bulletins published every year about this. I've seen it happen. The GPS times seems normal, but the elapsed and countdown time display random symbols that make no sense. I always use INT during February and GPS the rest of the year.
