All he saying is his timestamps don't have meaning, as he's not a Q level insider.
It's possible he's advised what date to poast any given information, or he just can't wait to shitpoast when he gets something dasting.
But I doubt decodes depend on his postings.
None the less, its good info, which gives us clues or confirmation to drop info.
Additionally, optically, he would be MSM crucified if he confirmed Q.
Only Trump can take those slings and arrows for the time being. And Q+ is certainly pushing the envelope.
