Hi Alan,
what makes you think that you get such a high resolution with the file dates? Most file systems only have a one second resolution (some even have less), meaning you have to wait for a second to actually see the value on disk change. So, even if the OS would use a higher resolution in its APIs, it would only be held in memory, not on disk. I'd question that bevavior, though - the APIs should not suggest a higher res than what the actual on-disk structure can support. Regardless - if some rare event would clear the in-memory cache, you'd get back the on-disk value with the lower resolution, and that could be what you're seeing. Unless I totally misunderstand what you're doing.

Thomas
