[time-nuts] Terrestrial Tides and Land Movement

[Bob Camp]

Hi

Tides are complicated once you get on land. They aren’t as simple as you might think when you are on the sea. There are people out there
who are “Tide Nuts” and every bit as obsessive as Time Nuts. 

Most of the time and most of the places, you get roughly a third of a meter change in altitude due to on tides on solid land. If you look at the speed
of light as 3 ns / meter - you get about 1 ns from tides.

I couldn't find anything useful, but I did discover that the Jersey Village area, about 2 miles northeast of me, is sinking about 2 inches a year.  So, my question is what effect do either of these, terrestrial tides or this local sinkage, have on timing accuracy?
