"By the decree enforcing the institution of the papacy in violation of the law of God, our nation [the United States] will disconnect herself fully from righteousness....  {Mar 199.4}
     As the approach of the Roman armies was a sign to the disciples of the impending destruction of Jerusalem, so may this apostasy be a sign to us that the limit of God's forbearance is reached, that the measure of our nation's iniquity is full, and that the angel of mercy is about to take her flight, never to return. The people of God will then be plunged into those scenes of affliction and distress which prophets have described as the time of Jacob's trouble. {Mar 199.5}

The "Great Time of Trouble" also called "The time of Jacob's Trouble", will be very short.  There are several reasons how we know this and the Spirit of God tells us several times that it will be a very short time from the "close of probation" to the appearing of Christ in the clouds of heaven !

All of the events that take place a few days berfore Christ comes, right until we see Him coming in the clouds of Heaven, are "timed" to happen in harmony with the very "times" given in "The Sanctuary Services" that God gave to Moses at Mt. Sinai.  All events connected with the Second Coming of Christ, will occur in the "Seventh Month" of the Sanctuary Calendar.

We need to understand that the "Seventh Month" of God's Calendar is not the same as the seventh month of the common calendar in use today.  In the "Gregorian Calendar", which is the calendar  used in the western world and in Europe, the seventh month is July, but, "The Seventh Month" of the Sanctuary Calendar, comes at the same time as September - October, is happening in the common calendar, but is called; "Tishri" !
