See man touch for more details. Some file systems support an additional entry in the inode regarding the creation time or birth time. However most tools and API have not yet been updated to read this extra information.

So even-though it could be there, it's not accessible. You can see that the newer stat function has a birth field, though the output seems incorrect. And via debugfs we can get the information crtime as I'm on ext4 file system. There is now since Kernel 4. Support for ext4 should be in the same kernel release 4.

There have been patches to add support to this new syscall in later Kernel releases: e. The up coming glibc will provide a function call to query this interface see Phoronix news about glibc statx support.
