I got confused by my own logic. :-\
Does the attached patch fix the issue?
It's based on "Netfilter: xt_LOG: Add timestamp support".

This patch lacks of description. If you don't make it myself, I have
to do it for you :-(

Please, send me patches following the standard format next time.

It was a "does this patch solve the problem"-Patch.
Does it fix the problem?

If so, I'll send an official one...

Sorry, that's too much overhead. I don't mind testing it, but I want
to apply it as soon as it fixes the problem ;-)

It seems to fix the problem. I have added the description and will
push to my git tree. Thanks.
