I built a plugin for wordpress that uses shortcodes and hooks. I need to recreate it in UNA. It pulls some data from the database. What is the equivalent of these?
1. ! is_user_logged_in() = this is the condition to see whether the user is logged in or not
2. user_login = this gets the user's account username
3. user_email = this gets the user's email address
4. time() = function that gets the current time from the mysql database
