When using rsync from pc to usb stick, it re-syncs unmodified files, which is
annoying with large backups.

In rsync man page, I found the following:

When transferring to FAT filesystems rsync may re-sync unmodified
files. See the comments on the --modify-window option.

And, the comment on the --modify-window option:

--modify-window
When comparing two timestamps, rsync treats the timestamps as
being equal if they differ by no more than the modify-window
value. This is normally 0 (for an exact match), but you may
find it useful to set this to a larger value in some situations.
In particular, when transferring to or from an MS Windows FAT
filesystem (which represents times with a 2-second resolution),
--modify-window=1 is useful (allowing times to differ by up to 1
second).

In fact, adding the option `--modify-window=2' seems to solve the problem.
However I wish to better understand the problem and to understand what I'm
doing. When listing files with `ls --full-time', no difference at all is shown
between pc and pendrive. So, why and what does `--modify-window' work for?

Thanks for any help
Rodolfo
