Reading the man page would tell you why and what to do:

--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).

Yes, (ex)FAT just doesn't have the resolution to represent some
timestamps, specifically it can only record even seconds.
