Yes, but that is a function of whether you are in a more or less accelerated
frame of reference.  The "standard" second is defined for the gravitational
conditions at "mean sea level" IIRC.

Moving to a location further from the centre of the earth does indeed make
the the clocks run faster, see e.g.:

Aren't there relativistic effects on Cs standard frequency because of
different gravity? (or is that really, the "same" frequency, just in a
different frame of reference)
