You are using (stat)[10] to get the ctime which I didn't think would work on Win32 systems. It says in the documentation for stat:

(*) Not all fields are supported on all filesystem types. Notably, the ctime field is non-portable. In particular, you cannot expect it to be a "creation time"; see Files and Filesystems in perlport for details.

In perlport it states:

ctime is creation time instead of inode change time (Win32).

Thanks for posting.
