The senior community rep has confirmed that these beta keys are intended for the Open beta. Not the closed beta. The dates are correct.
No. If you got a beta key from any source (other than an email from Funcom inviting you to private beta) you will be able to log in on the 15th of June through the 17th of June.
Additionally, if you have a beta key you can enter it now, create your account and download the beta of the game right now. You just have to wait to actually play
