The C standard doesn't specify a particular resolution, and you
can't even examine the value of CLOCKS_PER_SEC to determine the
particular resolution used.
Why not?
I see no reason.
7.23.2.1 The clock function
Synopsis
[#1]
#include <time.h>
clock_t clock(void);
Description
[#2] The clock function determines the processor time used.
Returns
[#3] The clock function returns the implementation's best
approximation to the processor time used by the program
since the beginning of an implementation-defined era related
only to the program invocation. To determine the time in
seconds, the value returned by the clock function should be
divided by the value of the macro CLOCKS_PER_SEC. If the
processor time used is not available or its value cannot be
represented, the function returns the value (clock_t)-1.
