Can you explain the difference between the Pre Wrath theory and the Post Tribulation theory in relation to time line?

The Post-Tribulation view, as the name implies, sees the rapture happening at the end of the seven years of Daniel’s 70th Week. In contrast, the Prewrath view sees the rapture happening at the opening of the sixth seal at an indefinite time during the second half of Daniel’s 70th Week. After the rapture the wrath of God is poured upon the world that has rejected Christ.
