Check the stats (i.e. use -v) and you should see that the whole file was
NOT sent -- just enough data to check the checksums and recreate the
file from the data that is already on the destination system.  The
reason that this optimized transfer occurs is because the file's size
and date are not identical, so rsync assumes that the file is different.
If you don't want to preserve the file times (using the -t option), you
might try using the -c option instead -- it's slow, though, but it does
only update files that are really different.
