a forwarded and with 1.16.3 reproducible bug report:

wget's manpage says:

>       -O file
>       --output-document=file
> ...
>           Use of -O is not intended to mean simply "use the name file instead of the one in the URL;" rather, it is
>           analogous to shell redirection: wget -O file http://foo is intended to work like wget -O - http://foo >
>           file; file will be truncated immediately, and all downloaded content will be written there.
>           For this reason, -N (for timestamp-checking) is not supported in combination with -O: since file is always
>           newly created, it will always have a very new timestamp. A warning will be issued if this combination is
>           used.

> -rw-r--r-- 1 user group 14649 Jun 13 17:12 test2

So the documentation is completely wrong here: '-O file' has the same timestamp of the last change of the web
page as the naked wget and behaves clearly different from '-O - > file' here.


Additional there is a comment on this from former maintainer Micah in this report but I want to be sure and verifiy if you think if is or is not something which might be corrected.
