Feature Request: Add Date Format to Short code

Would love to be able to choose what format I want the date to be in based on where and how this will be displaying.

Something like the WordPress option
https://ww.wp.xz.cn/plugins/extra-shortcodes/

using php (like the plugin does) is fine
http://php.net/manual/en/function.date.php
