Baba Pashuta Yid, if you are refering to the Zohar Chadash in Balak, there are different Girsaos. Perhaps it wasn’t meant to be really clear there either, especially being that it passed. We might have a Cheshbon but we don’t necessarily know the bumper date. But I’d still rather hear a better Terutz.
On a lighter note:
Perhaps you can’t know when he’ll come because some say that he already came.
