Indeed, on our Troubled Times site (or pending in the queue) are the following: 1. a finding that per the Earth Rotation Service and other official databanks, the Earth was slowing in its rotation some 54.87 seconds/year in 1986, and is now up to 64.0908 seconds/year (previous post) 2. a finding that the atomic clock has been adjusted WAY past the claimed inserted leap seconds the public is being led to believe are the only manipulations done to clocks by the clock-masters, the US Navy (below). Note: related chart From the Troubled Times Slowing TOPIC pending queue. @@@@@@@@@@@@@@@@@@@@@@@@@@@@ Comparison of our clocks to Atomic time results in an average of +40 sec/year for each the last 3 years (Jul 98 - Jul 01). This is added time making our clocks appear to run faster and faster each year. Josx is measuring actual earth rotation time and will publish his results once something definite can be determined. He has already indicated that the earth is rotating slower by .54 sec/day than his expensive accurate stopwatch. Assuming this watch was in sink with Atomic Time with in plus or minus .34 sec at the factory, then as he indicated he could already be measuring a slowing trend. Mathematics of Atomic Time comparison measurements Measure Drift "R" as the difference of Atomic time and individual Clock time (approximately 3 months intervals) = R1, R2, R3 . RN. Assumes clocks set back to atomic time beginning of each period otherwise determine a difference from last time for RN. (+ = Clock reading faster than Atomic Time. - = Clock reading slower than Atomic time) Change in drift then = R2 - R1, R3 - R2, ... RN - RN-1 Change in drift/day (CN) = (R2 - R1)/ D1, (R3 - R2)/ D2, ... (RN - RN-1)/DN-1 Where DN-1 = Number of days (calculated to 5 decimal places) between measurements. Next select the most reliable clocks using calculated standard deviation as a reference. Average all "change in drift/day (CN)" readings for all selected clocks during each time period or AvgCN . Average driFt curve AvgFN = first Integral of AvgCN per each time of measurement = (AvgC1)* D1, (AvgC1+AvgC2)* D2, (AvgC1+AvgC2+AvgC3)*D3, ... AvgFN Average comparison results to Atomic time = Integral of AvgDFN per each time of measurement = (AvgF1), (AvgF1+AvgF2), (AvgF1+AvgF2+AvgF3), ... This plotted becomes the 2nd integral results. Note that all straight line trends in the original data are filtered out, as desired. Only the changing situation is plotted in the results.
