No there isn't. That code is clearly Win32::ChangeNotify; that's not the same as ChangeNotify, which happens to not exist. Posting the code is also completely unnecessary - it cluttered the node and served no purpose. We all know where CPAN is.

Iif you're trying to "get the LAST_WRITE time of a file," then this may not be the right module for you. You use this module to check for changes to a file or group of files. You can't use this to just get a file's last modified time - you want stat for that. If you really do need this module, then you use it to set up a watcher that will get events when a file's last modified time changes. If you need to get the value of that time after it's been changed, you use stat.
