When The Temple is rebuild the Isaiah Jeremiah Daniel Ezekiel Joel and NT prophecies (like 2 Thessalonians 2 and Revelation) might be true, the time line could start there.
Could be true, could not be true.
Even when Temple is rebuild we are still not 100% sure whether what is genuine prophecy and what not.
Anyways different time lines from different scholars and Theology scientist are more or less consistent, so the time lines are correct, because its in the small and great prophets and NT, its the actual time line of The Bible (Tanakh and NT = New Testament), despite that they can still NOT predict the future, OR they are indeed genuine prophecies AS IN predicting the future
SO: Prophecies predicting the future, could be true, could not be true
Just type “timeline great tribulation” in Google Images
