Modified file Stamp changing by 1 sec??

when I was backing up files from Linux to Windows I had the same problem. It 
was because (some / all ???) Windows file systems have a file time 
resolutions of 2 seconds. Thus, if the file time on Unix was, e.g. 7:17, it 
had to be on Windows 7:16 or 7:18, and thus there was quite often a 1 second 
difference. However, you copied the files in the opposite direction, aren't 
you? Maybe you can figure out, if this is also the reason for your problem.
All the best,
