In windos there is a creation date associated with a file and in Linux there isn't. What happens to the creation date when that file is transfered from windos to a Linux system I assume the creation date becomes the last modification date?

The reason I ask I created a program in Windows (C#) that gets php files from a webserver and stores the files in chronological order in an Access database. Since I am converting to Linux I am planning on re-writing this program for Linux and still need chronological order. I think I am stuck just using modification time? (I plan on using C++ and SQLLite)
