+dit(bf(--date-only)) Normally rsync will skip any files that are
+already the same size and have the same modification time-stamp. With the
+--date-only option, files will be skipped if they have the same

+files have passed through a size-changing filter, e.g. for encryption.

dit(bf(--modify-window)) When comparing two timestamps rsync treats
