Sadly there's never been a creation time in Linux that you can get with a 
standard system call, there was an attempt 4-5 years ago to get xstat merged 
that would include creation time from filesystems that support it (like ext4) 
but it never went anywhere (for a variety of reasons).

FreeBSD has:

 st_birthtim  Time when the inode was created.

No idea when that was added!

All the best,
