First, to clarify what I meant by UTC being inaccurate. IMO, UTC is inaccurate as a measure of Earth rotation. It is precise in atomic seconds, but it is inaccurate for astronomical purposes. Accuracy is restored to a significant degree by DUT. It is precise to the degree that contributing clocks can be synchronized (nanosecond level, or as previous discussions conjecture, picosecond level). I am as usual insecure about this, and I would appreciate either confirmation or a more suitable alternative.
Second, I am now fascinated by the implications of lack of synch among virtual machines or real networks of distributed computers. I watched the YouTube video recommend in the previous thread. I do not understand this any way near to the others on this group, but I need to convince non-technical authorities that this matters. Any suggestions other than a two by four with lots of momentum -- and maybe a protruding nail? It is ironic that the shift in astrological signs made headlines this morning while the significance of Earth rotation and orientation parameters escapes notice.
