Can you have a Cs under zero acceleration and at zero temperature, the

are derived from the definition of the second, are any "primary

Isn't it defined for zero sea-level, that is standard acceleration?
"At its 1997 meeting the CIPM affirmed that:
This definition refers to a caesium atom at rest at a temperature of 0
K." - http://www.bipm.org/en/si/si_brochure/chapter2/2-1/second.html
Sea-level would be 1 g of acceleration, would it not?
