Don't you mean quite efficient... ?

I assume the email devrim receives is a list of files changed.
Rsync will do a diff on the files and copy the changes across.
If however the only difference is the timestamp, then the file
will still be listed in said email, since it's timestamp was updated.

I hope this weeds out any confusion.
