No Andrej is testing a problem we found with this particular log file.
Because the claim time window has psassed, he had to deliberaly hack
the date to test it.

This shows one of the reasons why the security check is important. I
think many people are questioning the need for security checks because
it is hard to imagine someone going to all the trouble to completely
fabricate a flight log. That would be very difficult, and it would take
a very sick mind to do something like this. But it is not that hard to
imaging someone taking a little creative license by "fixing" an
airspace bust, or some other "minor" problem in the flight log. It is
also possible to take an old log and recycle it, especially if it was
never claimed to OLC before.

Without the security check, deception like this would be completely
undetectable. In this case, the security checks worked, and the hacked
file was red flagged.
