According to: http://lwn.net/Articles/167897/
Linux kernels 2.6.16 and higher support nanosecond resolution time using hrtimer

According to: http://www.songho.ca/misc/timer/timer.html
gettimeofday() _should_ give microsecond resolution time and the only report I have seen it return less than microsecond was on an embedded processor

gettimeofday(), generally, but accuracy doesn’t go past milliseconds on all systems, sadly.

also if you’re intending to use QueryPerformanceCounter be sure to read this: http://support.microsoft.com/kb/274323

this might be helpful, too, for reference’s sake: http://www.stlsoft.org/doc-1.9/classplatformstl_1_1performance__counter.html
