on Linux while file metadata are in cache, timestamps may have high time resolution. When later fetched from disk they may have coarse resolution, e.g. whole seconds.
Yes, that is a known bug in older Linux kernels. As I understand it, the bug was fixed many years ago. (It broke GCC builds circa 2004[1] so there was a good deal of motivation to fix it.) I expect this problem is no longer relevant; if I'm wrong, Eli's suggestion would help to work around it.
