It differs in few minutes for "." entry. I guess that this can happen
when log file t_findfirst.log is being written to the current directory
which can affect ctime of ".". Probably same problem can happen also for
"..".
It is quite tricky to find out which entries could be modified during
current the test. It can depends on fs caches or other unknown things.
I remember that I read somewhere that FindFirstFile can return cached
values.
Quick fix which avoids this test for . and .. entries:

Now with this in place, I'm getting more errors later:
