In the 6 May 2022 edition of the NGS Weekly newsletter, there was mention of the linkage of heights of clocks to relative accuracies. Interesting discussion. The links in the blurb did not work on my system. I copied and pasted the Seattle Times article here: https://www.seattletimes.com/nation-world/get-ready-for-the-new-improved-second/

BTW, this issue prompted me to review Arne Bjerhammerƒ??s 1986 ƒ??Relativistic Geodesyƒ? Technical Report (NOAA TR NOS 118 NGS 36) available from the NGS site.

Anyone have links to research on this issue??ÿ

Here is a screen capture of the NGS blurb.

It looks like the research was published in NOS NGS Technical Memorandum 77 which is an update of NOS NGS Technical Memorandum 73 .

@mkennedy?ÿ

Thanks for the link.

I have not kept up like I hoped. Being retired for 14 years is no excuse.?ÿ

Cheers,

If one is interested in time and General Relativity you will also want to search at WWW.NIST.gov/physics

Look for Strontium one

name; Jun Ye

See JILA Atomic Clocks Measure Einstein's General Relativity at millimeter scale.

All very interesting
