title: Windows equivalent function of clock_gettime/clock_settime?
body: <p>I want to implement function <code>clock_gettime</code> and <code>clock_settime</code>.</p>
  
  <p>"<code>clock_gettime(CLOCK_PROCESS_CPUTIME_ID, timespec)</code>" is equivalent to "<code>GetProcessTimes</code>".</p>
  
  <p>but what is the equivalent function of "<code>clock_settime(CLOCK_PROCESS_CPUTIME_ID, timespec)</code>" ?</p>
  
  <p>I think "<code>SetSystemTime</code>" is equivalent to "<code>clock_settime(CLOCK_REALTIME, timespec)</code>", but "<code>clock_settime(CLOCK_PROCESS_CPUTIME_ID, timespec)</code>" is for counting from current process start, it's different from the <code>CLOCK_REALTIME</code>. </p>
