I'm just offering my perspective. I would conclude that "Time, Times and half a Time" is 3.5 years, 42 months and 1260 days.
As far as the "third temple" is concerned - I would say that is a false narrative. The "Temple of God" is not made by man's hands. Revelation 11: "1And there was given me a reed like unto a rod: and the angel stood, saying, Rise, and measure the temple of God, and the altar, and them that worship therein. 2 But the court which is without the temple leave out, and measure it not; for it is given unto the Gentiles: and the holy city shall they tread under foot forty and two months."
Notice he was told to measure the "temple of God, and the alter and them that worship therein". I would suggest this is not a physical structure being measured. And I would say we - all who worship the Father in Spirit and Truth thru the Son - are measured there, we fill the altar with our prayers. Those outside the temple are called "gentiles" but understand that to mean all the 'nations' of the world.
That brings us to "Israel" - the so-called 'Nation of Israel' - established in 1948 - is another creation of man, and a rather wicked one, (like the DC swamp and the Vatican and the UK royalty).
We're being manipulated to call a political state "Holy land" while it officially rejects Messiah Yahshua. It has been used to advance a war plan and an 'antichristian' agenda.
If 1948 was prophetically profound then it is due to the Dead Sea Scrolls finding.
We are going to recognize the true milestones in His plan. And the Two Witnesses be make sure that those who have the ears and eyes to hear and see, will understand.
