Ted Porter has written a very good analysis of the post by John Tng.
There are two very possible timelines being discussed in the forum of fivedoves.com and one is the one found in this article which starts the seven year covenant with the Nov4, 2008 elections and puts the second coming in the fall festivals of 2015. The other starts the seven years in the fall festivals of 2020 ending in the fall festivals of 2017.
Ted Porter is talking about the first of the two. This timeline would put the 1260 days that the two witnesses prophesy not in synchronization with the first half of the seven years which seems to be the wording of the book of Revelation.
In both cases the Rapture seems to be in September or October of this year.
For those not taken in the Rapture they may have to wait for the abomination of desolation defiling the Temple to know that they are at the middle of the seven years Tribulations.
