hwclock make clock_gettime not accurate

HI guys. I'm doing some tests about clock_gettime. And I found that clock_gettime will be affected by hwclock. It makes clock_gettime slip advance some milliseconds. Actually, each line prints out every 1ms. $ ./a.out -r CLOCK_MONOTONIC 130 ↵ Using delay=1 ms
