date addition in bash doesn't work. Can someone explain why?
I have followed examples on numerous stack exchange websites and various other tutorial websites on how to do date math. I have tried linux (on containers) I get the exact same error:
$ docker run -it bash date -d '2014-11-19T15:40:30+10d'
date: invalid date '2014-11-19T15:40:30+10d'
bash version:
$ docker run -it bash bash --version
