      If you want to get the time difference with high precision from the
      user space application use clock_gettime( The man page may be available
      on linux so check solaris or Tru64 box around. If not give a google
      serach ) and use CPU resolution. Inside kernel check for rdtsc().

      Make sure your Time stamp counter doesn't overflow. That is you are
      measuring a long time gap.
