Right, and if you want, you can use the --size-only arg to rsync to
disable the timestamp check and made it only a size check ... so, if the
size doesn't change, the page wasn't actually modified ... and, I can't
think of many situations where if hte file changed, the size wouldn't
change by *at least* one character, but I imagine it could happen ...
