Created time doesn't work on Unix

The created time doesn't exist on standard Unix filesystems, there's

mtime: Lastmodified time
atime: Last accessed time
ctime: Last metadata change time.

The EXT4 filesystem does have a file created time, but it can only be accessed by the superuser.

A file created time is available on Windows, but this is still technically inaccurate as it doesn't say when the level was created, just when the file was last copied.

Please add a new field to the level properties to be populated when a level is created and suppress the display of the (wrong) time when the property doesn't exist or has a "null" value.

Finding the file created time on an EXT4 filesystem using debugfs and sudo.

xstat() {
  for target in "${@}"; do
    inode=$(ls -di "${target}" | cut -d ' ' -f 1)
    fs=$(df "${target}"  | tail -1 | awk '{print $1}')
    crtime=$(sudo debugfs -R 'stat <'"${inode}"'>' "${fs}" 2>/dev/null | 
    grep -oP 'crtime.*--\s*\K.*')
    printf "%s\t%s\n" "${crtime}" "${target}"
  done
}
