From 1.12 manual:

EXIT STATUS
       Wget may return one of several error codes if it encounters problems.

       0   No problems occurred.
       1   Generic error code.
       2   Parse error---for instance, when parsing command-line options, the 
.wgetrc or .netrc...
       3   File I/O error.
       4   Network failure.
       5   SSL verification failure.
       6   Username/password authentication failure.
       7   Protocol errors.
       8   Server issued an error response.

       With the exceptions of 0 and 1, the lower-numbered exit codes take 
precedence over higher-numbered ones, when multiple types of errors are 
encountered.

       In versions of Wget prior to 1.12, Wget's exit status tended to be 
unhelpful and inconsistent. Recursive downloads would virtually always return 0 
(success), regardless of any issues encountered, and non-recursive fetches
       only returned the status corresponding to the most recently-attempted 
download.


So wget -N always retuns 0 on success (tested 1.12 too). Success is both 
downloading a file and not downloading it due to current timestamp.


I guess I'll use the ugly method for now.
