Lost Minutes

The figures I use are old tables giving sun and moon risings. These are old documents I loaded from the net at that time. I compare them with official figures given on French newspapers, etc. The old figures are without shifts [changes by the Navy] for this period. A simple comparison between both sources seems to show a 9-minute shift. As I am concerned, I believe these [recent] time shifts [changes by the Navy] are not real but differences due to human actions to hide evidence [of slowing]. The old tables (assumed to be true and shift-free) I use for my comparisons are following.
