Sorry, I don't follow.

Is the problem that kLIBC utimes operates on file systems whose time stamps resolution are 2 seconds? I recall that this is a problem in older Microsoft file systems. If so, we should change m4/utimes.m4 to use even time stamps in its test, rather than odd ones, so that HAVE_WORKING_UTIMES is defined on kLIBC and we don't need to change lib/utimens.c.

If it's some other problem, then what is the problem?
