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,
Chris
