Everyone today has been complaining about not getting their ghost shell. It is the 23rd (when you are getting your ghost). You should hold off on the complaint until tomorrow when it actually makes sense if you haven't gotten your ghost yet.
All of these "not getting my ghost" posts are clogging up the #Help forums. We can't help people who have other questions and issues.
Bungie has not released any specific time, only that the ghosts will be given some time today. Here is a link to Magis123's post: https://www.bungie.net/en/Forum/Post/193305904/0/0
Have a good day fellow guardians. :)
