For example, i have some file on local windows system:
-------
Create: aug 10 2009., 13:24:52
Change: aug 10 2009, 13:24:52
Open: may 20 2010, 17:31:32
-------
And then i open it, make some changes and close it. So:
-------
Create: aug 10 2009, 13:24:52
Change: oct 7 2010, 12:31:51
Open: may 20 2010, 17:31:32
------

changed only the date of the modification. This is right.

And now i open samba share. Take some file:
-----
Create:  sep 3 2010, 14:42:25
Change: sep 3 2010, 14:42:25
Open: sep 8 2010 г., 0:12:54
-----
I open it, make NO changes and close it:
-----
Create: oct 7 2010, 12:31:00
Change:  oct 7 2010, 12:31:00
Open: oct 7 2010, 12:31:03
-----
As you can see all the parameters have changed! That`s wrong!
