Of the coming Day of Judgement, then no one knows, good angel, the Prophet, or Apostle, this problem is a matter of supernatural and only Allah Subhanahu wa Ta'ala alone knows. As mentioned in the verses of Al-Qur'an and the hadiths of the Prophet sallallaahu 'alaihi wa sallam is saheeh.
"They ask thee concerning the Hour: 'When is incurred.' Say: 'Verily the knowledge of the Day of Resurrection it is the Lord on my side, no one can explain the time of his arrival but Him. Doomsday is very heavy (for beings haranya turmoil) is in the heavens and on earth. Last Hour will not come to you but suddenly. 'They ask you as if you really know about it. Say: 'Verily the knowledge of the Day of Resurrection it is with Allah, but most people do not know.' "[Al-A'raaf: 187]
His words also:
"Men ask thee concerning the Hour. Say: 'Verily the knowledge of the Hour is with Allah only.' And do ye, O (Muhammad), may be the Hour is near the time. "[Al-Ahzaab: 63]
Also, upon whom be peace when the angel Gabriel came to Prophet Muhammad sallallaahu 'alaihi wa sallam and asked:
"All flesh to me, when there Doomsday?"
Then the Prophet sallallaahu 'alaihi wa sallam answer:
"It is not people who were asked more aware than anyone who asks." 
Although the time of the day of Judgement no one knows, but Allaah tells His Messenger sallallaahu 'alaihi wa sallam about the signs of the Apocalypse. Then the Prophet sallallaahu 'alaihi wa sallam told his community about the signs of Doomsday. The scholars divided it into two: (first) small signs and (second) large signs.
Small signs very much and has been happening since time immemorial and will continue to occur among them is the death of the Prophet Muhammad sallallaahu 'alaihi wa sallam, the emergence of many libel, slander emergence from the east (Iraq), the emergence of firqah Khawarij, the emergence of people who claim to be Prophet, the loss of trust, the appointment of science and rampant stupidity, the number of adultery, the number of people who play music , many people who drink wine (liquor) and the spread of gambling, the mosques are decorated, many tall buildings, slave gave birth to her master, the number of murders, many kesyirikan, many people who decide silaturrahim, many people are stingy, the death of the scholars and righteous people, many people are learning to the People of the border patrol, the number of women who dressed but naked , and others . 
There are so many arguments about this, including the words of the Prophet sallallaahu 'alaihi wa sallam:
"Look at the six signs of the Day of Judgement: (1) wafatku, (2) the conquest of Baitul Maqdis, (3) plague of death (diseases affecting the animals that died suddenly) that attacking you like qu'ash disease that attacks the goat, (4 ) abundance of wealth to a person who granted him 100 dinars, he was not willing to accept it, (5) the emergence of slander that does not leave one's house but the Arabs were definitely into it, and (6) the peace between you and the children of Asfar (the Romans), but they break them and come to you with 80 large groups of troops. Each group consisted of 12 thousand people. "
Also the words of the Prophet sallallaahu 'alaihi wa sallam
"Verily among the signs of the Day of Judgement are: the appointment of science, the spread of ignorance, drank wine, and rampant adultery." 
Then the emergence of signs of a second, that the signs of the Apocalypse that as a sign of Judgement day has been nearby. The author dedicated discussion about some of the signs of the Apocalypse that, because there are some people (groups) who reject the signs of these based on reason, ra'yu and passions. Though the Ahlus Sunnah scholars have discussed this issue in the books of tafsir, hadith books and the books' their faith.
The discussion of this issue following the Ahlus Sunnah scholars in their books, like in the book Syarhul 'Aqiidah ath-Thahaawiyyah  and other books.
Ahlus Sunnah wal Jama believe about any signs of a great Judgement (unsuccessful) such as,  The release of Imam Mahdi, Dajjal, the descent of Prophet Jesus, upon whom be peace from heaven, Gog and Ma'juj, the rising sun from the west, and others.
"What they later-later is nothing but the arrival of the angel to them (to kill them), or the coming of your Lord, or the arrival of some of the signs of thy Lord is not useful anymore for his own faith in someone who has not believed before that, or he (yet) stree-sahakan good faith in the future. Say: 'Wait ye! We were waiting (for this).' "[Al-An'am: 158]
Prophet sallallaahu 'alaihi wa sallam said:
"Doomsday is not going to happen so that you see ten signs: (1) drowning the earth's surface in the east, (2) drowning the earth's surface in the west, (3) the earth's surface sinking in the Arabian Peninsula, (4) discharge of smoke, (5) discharge Dajjal, (6) the release of large animals, (7) discharge wa Ma'juj Gog, (8) the rising sun from the west, and (9) fire coming out from the bottom of the earth 'Eternity, the human herd, and (10) falling 'Isa ibn Maryam, upon whom be peace.
