+dit(bf(--modify-window)) When comparing two timestamps rsync treats
+the timestamps as being equal if they are within the value of
+modify_window. This is normally zero, but you may find it useful to
+set this to a larger value in some situations. In particular, when
+transferring to/from FAT filesystems which cannot represent times with
+a 1 second resolution this option is useful.

 dit(bf(-c, --checksum)) This forces the sender to checksum all files using
 a 128-bit MD4 checksum before transfer. The checksum is then
 explicitly checked on the receiver and any files of the same name
