The difference is complicated to explain because the code includes logic
to optimise bandwidth use by not downloading a directory listing from the
server if the directory does not appear to have changed since the last
run; and this changes how a file is determined to have changed. I report
different messages in these two cases only to help with debugging.
"not modified since last upload" means that:
* the directory has changed locally since we last uploaded it;
* so we did download the directory listing from the server;
* the file is already on the server;
* the modification time of the file has not changed.
"outside sync window" basically means that we deduced that the file hasn't
changed without asking the server.
I recommend that you ignore the difference, compare your backups
regularly, and if you're missing any files then report the problem and we
can understand what happened by looking at the logs.
