The time turners were all destroyed. In HBP when they went to the Department of Mysteries, the room with the bell jar and the butterfly was the room that contained the time turners. I think when they destroyed the bell jar, they destroyed this magic for the time being. Hermione even mentions it, saying something to the effect of "too bad we destroyed them last year..." (not exact quote)
The Patronus being able to send messages is too far advanced for Harry. It is said that this magic hasn't been achieved by Harry. The whole wizarding world didn't really know he could perform such a great Patronus until HBP so that's probably why no teachers taught him the message version, although the Order could have.
Ohh, I see, they maybe didn't destroy all the time turners, but maybe the mother ship that made them all work. That I can buy.
