> In fact, on Unix, I have the impression that just checking ctime is enough, as any change to the file changes that timestamp, and it cannot be changed manually.

I believe this is incorrect, but I'm not sure how it is done.

    I've looked at some freely available C source code to change ctime of files, and wht it does is change the clock time, change a file's ctime to the "current time", and change the clock back. (I'll link to it if I can find it back.)

    If this hack is the only way to achieve it, I think you can state it can't be done.
