Yes this is true!
It can only happen at the end of the age just before Jesus returns. By comparing where the words "great tribulation" is used gives us a solid time frame context:
21“For then there will be a great tribulation, such as has not occurred since the beginning of the world until now, nor ever will.
22“Unless those days had been cut short, no life would have been saved; but for the sake of the elect those days will be cut short.
23“Then if anyone says to you, ‘Behold, here is the Christ,’ or ‘There
He is,’ do not believe
him. 24“For false Christs and false prophets will arise and will show great signs and wonders, so as to mislead, if possible, even the elect.
25“Behold, I have told you in advance.
13Then one of the elders answered, saying to me, “These who are clothed in the white robes, who are they, and where have they come from?”
14I said to him, “My lord, you know.” And he said to me, “These are the ones who come out of the great tribulation, and they have washed their robes and made them white in the blood of the Lamb.
The context where all arrive out of the great tribulation is just after the sixth seal and before the trumpet judgments begin. These same three signs are what Jesus told us to watch for when the great tribulation is cut short. This is when His parousia takes place, the rapture/resurrection, and His presence is known and felt throughout the earth.
The linkage with Mat 24 and the writings of Paul is clear when you compare the word parousia and "presence" (before the face) in Rev 6. Rev 19 does not have this word. Why? Because He already came at the sixth seal! He is already present and active with His judgments (His year of payback for the controversy of Zion Is. 34:8) and is getting ready to take possession of the earth after the last bowl.
This information and knowledge changed my viewpoint from pre and post trib, and may help others who are searching.

12I looked when He broke the sixth seal, and there was a great earthquake; and the sun became black as sackcloth
made of hair, and the whole moon became like blood;
13and the stars of the sky fell to the earth, as a fig tree casts its unripe figs when shaken by a great wind.
14The sky was split apart like a scroll when it is rolled up, and every mountain and island were moved out of their places.
15Then the kings of the earth and the great men and the commanders and the rich and the strong and every slave and free man hid themselves in the caves and among the rocks of the mountains;
16and they said to the mountains and to the rocks, “Fall on us and hide us from the presence of Him who sits on the throne, and from the wrath of the Lamb;
17for the great day of their wrath has come, and who is able to stand?”
29“But immediately after the tribulation of those days THE SUN WILL BE DARKENED, AND THE MOON WILL NOT GIVE ITS LIGHT, AND THE STARS WILL FALL from the sky, and the powers of the heavens will be shaken.
30“And then the sign of the Son of Man will appear in the sky, and then all the tribes of the earth will mourn, and they will see the SON OF MAN COMING ON THE CLOUDS OF THE SKY with power and great glory.
31“And He will send forth His angels with A GREAT TRUMPET and THEY WILL GATHER TOGETHER His elect from the four winds, from one end of the sky to the other.
