Wordpress Cron: Running as which user?

Question

I'm writing a plugin. It has some job to be execute by wp_cron. Now within the script, it create/edit some posts automatically. So which user will be running the cron job?

Also I notice it failed when calling WP_Filesystem()

Answer 1

Well I've found out that it's running as no one, as get_current_user_id() returns 0
