When I type the following:

$ IFS=$'\n'; arr=( $(stat "/bin/bash") ); for i in ${arr[@]} ; do echo $i ; done
  File: '/bin/bash'

I see the Birth Date for /bin/bash is null / empty. When is this field ever used and what purpose might it have in Linux when it works?

I appreciate there is a shorter way of using stat but this came up during development cycle and I copy and pasted.
