I tend to agree with you. As much as we study and think we have figured out what God is telling us from the Scriptures, about the time we think we are right, He tosses a curve ball at us.
We can study and study, but in the end more times than not we can do is actually play Johnny come lately in realizing He was telling us about something that happened, not is going to happen.
All the great theologians of the time tried their best to know when Christ was arriving the first time, and yet all those who were alive when it happened missed the boat. Obviously their hearts were not prepared for what He was actually going to come as. A servant, not a King. At least of this world and the first time.
Which tells me what is going to happen when He returns. I see many missing the boat who are sure they know the signs of the times.
The best we can hope for is to have our hearts ready for Him, and not worry so much about when the day is going to be.
Although it is all good for study and preparing our minds and hearts to be approved.

The men taught by the instructions of the prophet Daniel knew exactly when and where he was to be born by studying the astronomy of the constellation Bethula (Virgo in pagan lingo).
The late professor D. James Kennedy had a theory on how his second coming was going to be foretold by the constellations Large Sheepfold, and Small Sheepfold (Big Dipper, Little Dipper) as they foretold Yeshua’s two “sheep folds” to which he was sent by the Father, rejoining as prophesied by Ezekiel in chapter 37.
