NIST seems to place time a priori to space ?

Counting oscillations of a specifically prepared
emission of radiation is the basis of time ?

A theory that defines the relation between space
and time must also define a new standard of measuring
the units ?

SPACE:
The meter is the length of the path travelled by light
in vacuum during a time interval of 1/299 792 458
of a second.

TIME:
The second is the duration of 9 192 631 770
periods of the radiation corresponding to the
transition between the two hyperfine levels of the
ground state of the cesium 133 atom.
