Sure, scalar time_t values are used underneath, and I didn't say
otherwise.  That's what time_t is for.  The kernel even increments the
time_t clock, most of the time, as if it's a linear count of seconds,
which is how it behaves on the small scale outside the immediate
vicinity of leap seconds.  But a kernel that knows about leap seconds
then introduces a discontinuity in the scalar value, somewhere near each
leap, to maintain the scalar<->UTC relationship.

Indeed.  The two definitions are separate, but match in most of their
design features.
