Getting file creation (birth) time on posix systems using statx Description Use statx (extended stat) to get the creation date of files on Linux systems. I'm not sure that this is the best way to go about implementing this so please do comment if there is a better way to do it.
It's possible to set POSIX permissions for a file once the file exists. The code below does this. However, that code also has a file race in which the file is opened with what can be loose permissions (CREATION) which I then lock down later (SECURED). In between someone could have modified the file, causing problems.

File Creation Time in Linux. Jun 23, 2019 tech linux filesystem. The stat utility can be used to retrieve the Unix file timestamps namely atime, ctime and mtime. Of these, the benefit of mtime which records the last time when the file was modified is immediately apparent. On the other hand, atime 1 which records the last time the file was accessed has been called “perhaps the most stupid Unix design idea of all times”.
Note that on Linux this requires coreutils 8.31, glibc 2.28 and kernel version 4.11 or newer.
