These days, the length of a second is defined by the difference in frequency between two ground-state energy levels of a caesium-133 atom, which works out to 9192631770 cycles per second. No need to check tide tables.

That definition is still relative. It still requires as additional factor the place where the measurement is taken, due to Einstein's theories.
That's why I proposed changing the second definition to 9192631770 cycles in a gravitational field equivalent to that of Greenwich.
