Basically, your patch does the right thing, as MSDN says
"If times is a NULL pointer, the modification time is set to the current local time."
-- like POSIX.

Finally, why not merge the two? After all, it's one change, and several tests.

Why do you call it test_utime() since you don't verify the effects of utime()?
