Sorry

        Well, I'd like to apologize, many people want to stop talking of the
problem of time measurement and I add a posting about it. That's the problem
of jet lag: I receive mails, I read them one by one and sometimes answer to
one of them, and then I find in a later post I didn't read yet that the
answer was already given. Next time I'll try to read everything before
answering to any mail (but it's difficult when you have received more than
80 mails).
