The Recruit A Friend announcement page makes no mention of any such month long trial. The only bonus given to the friend who was recruited is the Friendship Circlet. There's no game time included with that.

Now, there is also a Free Trial program that's not associated with the Recruit A Friend program. Anyone who wants to try the game can do so on PC for 14 days. (Last I heard they were planning on adding a similar 14-day Free Trial option for PS3 and PS4, but I'm not certain if that's out yet.) That only requires that you haven't had the game through a paid or beta version before, no recruiting needed.
