The prophecy of the destruction of Jerusalem was a time prophecy first given by Ezekiel and reiterated by Jesus Himself. As a time prophecy, Ellen White recognizes a dual fulfillment of it for the time of Jerusalem's visitation in 70 AD and for our time.

If dual fulfillments are shown to occur for one prophecy, such as this one, how can one make a blanket statement regarding all time prophecies that they cannot have dual fulfillment?

Green Cochoa: But then, if you wish to reject Ezekiel's prophecy, we still have that of Jesus Himself.

Rosangela: As far as I know, Jesus didn't say when this would happen, either.

In regards to 70 A.D., Jesus never said that the destruction would/should take place in exactly 40 years after his death (which would actually be 71 A.D.) That is just what is commonly assumed. What Jesus said in Mark 13:30 was that the generation of people listening to him then, especially the ones (i.e., the knowledgeable adults) who were rejecting Him (cf. Luke 17:25) would not die before what He had said would be fulfilled. If that “generation” is considered to start from people aged 20, and life expectancy was ca. 70-80 years (Psa 90:10a), then Christ was here seeing ca. 81-91 A.D. as the limits.

As far as I know, Jesus didn't say when this would happen, either.

Matthew
24:1 And Jesus went out, and departed from the temple: and his disciples came to [him] for to show him the buildings of the temple.
24:2 And Jesus said unto them, See ye not all these things? verily I say unto you, There shall not be left here one stone upon another, that shall not be thrown down.
...
24:15 When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand:)
24:16 Then let them which be in Judaea flee into the mountains:
24:17 Let him which is on the housetop not come down to take any thing out of his house:
24:18 Neither let him which is in the field return back to take his clothes.
24:19 And woe unto them that are with child, and to them that give suck in those days!
24:20 But pray ye that your flight be not in the winter, neither on the sabbath day:
...
24:33 So likewise ye, when ye shall see all these things, know that it is near, [even] at the doors.
24:34 Verily I say unto you, This generation shall not pass, till all these things be fulfilled.

And the LORD'S anger was kindled against Israel, and he made them wander in the wilderness forty years, until all the generation, that had done evil in the sight of the LORD, was consumed. (Numbers 32:13)

And the space in which we came from Kadeshbarnea, until we were come over the brook Zered, [was] thirty and eight years; until all the generation of the men of war were wasted out from among the host, as the LORD sware unto them. (Deuteronomy 2:14)

Psalms
22:16 For dogs have compassed me: the assembly of the wicked have enclosed me: they pierced my hands and my feet.
22:17 I may tell all my bones: they look [and] stare upon me.
22:18 They part my garments among them, and cast lots upon my vesture.
22:19 But be not thou far from me, O LORD: O my strength, haste thee to help me.
22:20 Deliver my soul from the sword; my darling from the power of the dog.
...
22:27 All the ends of the world shall remember and turn unto the LORD: and all the kindreds of the nations shall worship before thee.
22:28 For the kingdom [is] the LORD'S: and he [is] the governor among the nations.
22:29 All [they that be] fat upon earth shall eat and worship: all they that go down to the dust shall bow before him: and none can keep alive his own soul.
22:30 A seed shall serve him; it shall be accounted to the Lord for a generation.

Forty years long was I grieved with [this] generation, and said, It [is] a people that do err in their heart, and they have not known my ways. (Psalm 95:10)

For David, after he had served his own generation by the will of God, fell on sleep, and was laid unto his fathers, and saw corruption: (Acts 13:36) {see also text below}

David [was] thirty years old when he began to reign, [and] he reigned forty years. (2 Samuel 5:4)

Christ gave His disciples a sign of the ruin to come on Jerusalem, and He told them how to escape: "When ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh. Then let them which are in Judea flee to the mountains; and let them which are in the midst of it depart out; and let not them that are in the countries enter thereinto. For these be the days of vengeance, that all things which are written may be fulfilled." This warning was given to be heeded forty years after, at the destruction of Jerusalem. The Christians obeyed the warning, and not a Christian perished in the fall of the city. {DA 630.3}
"Pray ye that your flight be not in the winter; neither on the Sabbath day," Christ said. He who made the Sabbath did not abolish it, nailing it to His cross. The Sabbath was not rendered null and void by His death. Forty years after His crucifixion it was still to be held sacred. For forty years the disciples were to pray that their flight might not be on the Sabbath day. {DA 630.4}

As the attention of the rejected One was called to the magnificence of the temple, what must have been his thoughts! The view before him was indeed beautiful; but he said, sadly: I see it all, and the buildings are indeed wonderful. You point to these stones as apparently indestructible, but listen to my words. I tell you solemnly that the day will come when there shall not be left one stone upon another that shall not be thrown down. Forty years after Christ uttered this prediction, his words were fulfilled to the letter. In the siege of Jerusalem it is stated that more than a million people perished, and that many were led into captivity. {RH, December 13, 1898 par. 12}
Christ's words had been spoken in the hearing of a large number of people; but when he was again alone, Peter, James, John, and Andrew came to him, saying, "Tell us, when shall these things be? and what shall be the sign of thy coming, and of the end of the world?" {RH, December 13, 1898 par. 13}
In his answer, Jesus did not take up separately the destruction of Jerusalem and the last great day of his coming. He mingled the description of these two events. When he spoke of the destruction of Jerusalem, his words referred also to the final destruction that will take place when the Lord rises out of his place to punish the world for its iniquity. The entire chapter in which are recorded Christ's words regarding this, is a warning to all who shall live during the last scenes of this earth's history. {RH, December 13, 1898 par. 14}

Next, how long is a Biblical generation:

And the LORD'S anger was kindled against Israel, and he made them wander in the wilderness forty years, until all the generation, that had done evil in the sight of the LORD, was consumed. (Numbers 32:13)

GC, a generation refers to all the people born more or less at the same point in time. This is the meaning in all the passages the word is used in the Bible.
David served his generation (all the people who were born more or less at the same point in time as he) for 40 years. It could be 20, or 30, or 50. This doesn't matter.
The generation who came out of Egypt was in the wilderness for 40 years. Note that the Bible doesn't say that they spent one generation in the wilderness, but that that generation spent 40 years in the wilderness. It's a big difference.

Prophecy not only foretells the manner and object of Christ's coming, but presents tokens by which men are to know when it is near. Said Jesus: "There shall be signs in the sun, and in the moon, and in the stars." Luke 21:25. "The sun shall be darkened, and the moon shall not give her light, and the stars of heaven shall fall, and the powers that are in heaven shall be shaken. And then shall they see the Son of man coming in the clouds with great power and glory." Mark 13:24-26. The revelator thus describes the first of the signs to precede the second advent: "There was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood." Revelation 6:12. {GC 304.1}

These signs were witnessed before the opening of the nineteenth century. In fulfillment of this prophecy there occurred, in the year 1755, the most terrible earthquake that has ever been recorded. Though commonly known as the earthquake of Lisbon, it extended to the greater part of Europe, Africa, and America. {GC 304.2}

Twenty-five years later appeared the next sign mentioned in the prophecy--the darkening of the sun and moon. What rendered this more striking was the fact that the time of its fulfillment had been definitely pointed out. In the Saviour's conversation with His disciples upon Olivet, after describing the long period of trial for the church,--the 1260 years of papal persecution, concerning which He had promised that the tribulation should be shortened,--He thus mentioned certain events to precede His coming, and fixed the time when the first of these should be witnessed: "In those days, after that tribulation, the sun shall be darkened, and the moon shall not give her light." Mark 13:24. The 1260 days, or years, terminated in 1798. A quarter of a century earlier, persecution had almost wholly ceased. Following this persecution, according to the words of Christ, the sun was to be darkened. On the 19th of May, 1780, this prophecy was fulfilled. {GC 306.1}

May 19, 1780, stands in history as "The Dark Day." Since the time of Moses no period of darkness of equal density, extent, and duration, has ever been recorded. The description of this event, as given by eyewitnesses, is but an echo of the words of the Lord, recorded by the prophet Joel, twenty-five hundred years previous to their fulfillment: "The sun shall be turned into darkness, and the moon into blood, before the great and terrible day of the Lord come." Joel 2:31. {GC 308.1}

In 1833, two years after Miller began to present in public the evidences of Christ's soon coming, the last of the signs appeared which were promised by the Saviour as tokens of His second advent. Said Jesus: "The stars shall fall from heaven." Matthew 24:29. And John in the Revelation declared, as he beheld in vision the scenes that should herald the day of God: "The stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind." Revelation 6:13. This prophecy received a striking and impressive fulfillment in the great meteoric shower of November 13, 1833. {GC 333.1}

Thus was displayed the last of those signs of His coming, concerning which Jesus bade His disciples: "When ye shall see all these things, know that it is near, even at the doors." Matthew 24:33. After these signs, John beheld, as the great event next impending, the heavens departing as a scroll, while the earth quaked, mountains and islands removed out of their places, and the wicked in terror sought to flee from the presence of the Son of man. Revelation 6:12-17. {GC 334.2}

If we look carefully at the prophecies we put in the past we'll find that many of the particulars of them don't have a complete fulfillment.
