No. The article specifically says that after it the system time gets to ,600, it is decremented by one and there is specific code in the code that returns the system time to applications that makes it stand still. The second isn't *NOT* repeated. Repeat: The second is *NOT* repeated in

(Oops, I forgot to attach the attachment!) Thank you, Warner, for your thoughtful reply enumerating the reasons that you are in camp #2. It caused me to research the matter further, so that I could understand your point of view. I purchased a copy of the IEEE 1588 standard and began to study
