Your previous explanation of the problem was very clear...
Here is an example when I do:
# inotifywait -m -e access --format "%T %f" --timefmt "%D %T" -r /home/jd/tmp
Setting up watches.  Beware: since -r was given, this may take a while!
Watches established.
$ less toto.php

It detected my read access to the file 'toto.php' in '/home/jd/tmp'
