I've just been bitten by an annoying quirk, experienced on 2 different WindowsXP systems.

When copying a file from an NTFS partition to a FAT32 device, the new file's modified date is sometimes changed by 1 or 2 seconds.
This became apparent in a file syncronization program I have that compares mod dates and copies newer files over the older, and in this case can never catch up since the mod date is a moving target.

Only some files do this, and they do it consistently. It seems to have something to do with the original mod date value, maybe different number systems are rounding or something??

I tried doing a drag-n-drop copy within Windows Explorer and it did the same thing.

Anyone else see this behavior?
