Reminds me of the North Korean software developers writing iPhone apps Wink

Ok, but that doesn't yet imply that gettimeofday() in Linux is less accurate "because the Linux kernel is written in C". Anyway, I just googled a bit and it seems that clock_gettime() should be very accurate on kernel 2.6.18 and later. And since that kernel, gettimeofday() also uses clock_gettime(). On recent kernels the overhead seems to be low as well:

The only benefits to gettimeofday() is that on powerpc, ia64 and x86_64, it is implemented with a userspace-only vsyscall/vdso, which avoids the syscall overhead. However, recent x86_64 kernels have added support for vsyscall clock_gettime() as well.

It seems the timing source used might depend on intel/amd and power saving settings... The technical issues mentioned should apply to both Windows and Linux, though.
