Note sure if this has been raised here before, but a new paper by Duncan Agnew is available.
"Time and tide: pendulum clocks and gravity tides" https://hgss.copernicus.org/articles/11/215/2020/ It thanks TVB in the "Acknowledgements", so hopefully it is safe to mention it here. I enjoyed reading it. On a personal note, it "sort of" ties in with a project I am currently playing with (clocks and ocean tides) where I have written a new algorithm to improve the accuracy of setting a conventional Tide Clock. Whilst doing this, I wondered whether I could change my 100 year old family heirloom Ansonia Kitchen clock, to run (at a more leisurely rate in its retirement) as a Tide Clock, by increasing the pendulum period by: --------------------------------------------------------------------------------------------- M2 constituent of the Harmonic Tide Speed = 28.984104 (degrees per hour) Period = 360 / Speed = 12 Hours 25 Minutes 14.165 Seconds Increase Pendulum Period by 12:25:14.165 / 12:00:00 = 1.035050 --------------------------------------------------------------------------------------------- There is only 1mm of thread left on the pendulum shaft, but I was very pleased to be able to regulate it to within the thermal limitations of a steel pendulum rod ! Not exactly approaching "Time Nuts" precision though !
