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
