Here are the verses in question..
Ezekiel 9:1-11
1 He cried also in mine ears with a loud voice, saying, Cause them that have charge over the city to draw near, even every man with his destroying weapon in his hand.
2 And, behold, six men came from the way of the higher gate, which lieth toward the north, and every man a slaughter weapon in his hand; and one man among them was clothed with linen, with a writer's inkhorn by his side: and they went in, and stood beside the brasen altar.
3 And the glory of the God of Israel was gone up from the cherub, whereupon he was, to the threshold of the house. And he called to the man clothed with linen, which had the writer's inkhorn by his side;
4 And the Lord said unto him, Go through the midst of the city, through the midst of Jerusalem, and set a mark upon the foreheads of the men that sigh and that cry for all the abominations that be done in the midst thereof.
5 And to the others he said in mine hearing, Go ye after him through the city, and smite: let not your eye spare, neither have ye pity:
6 Slay utterly old and young, both maids, and little children, and women: but come not near any man upon whom is the mark; and begin at my sanctuary. Then they began at the ancient men which were before the house.
7 And he said unto them, Defile the house, and fill the courts with the slain: go ye forth. And they went forth, and slew in the city.
8 And it came to pass, while they were slaying them, and I was left, that I fell upon my face, and cried, and said, Ah Lord God! wilt thou destroy all the residue of Israel in thy pouring out of thy fury upon Jerusalem?
9 Then said he unto me, The iniquity of the house of Israel and Judah is exceeding great, and the land is full of blood, and the city full of perverseness: for they say, The Lord hath forsaken the earth, and the Lord seeth not.
10 And as for me also, mine eye shall not spare, neither will I have pity, but I will recompense their way upon their head.
11 And, behold, the man clothed with linen, which had the inkhorn by his side, reported the matter, saying, I have done as thou hast commanded me.

It is either prophecy of from Ezekiel's time, which comes from that it more or less conveys the idea that Ezekiel 9 was fulfilled in the past as an historical event, except for that it looks like a end time fulfilment during the Seven Last Plagues and the Second Coming. On the surface the reasons for the historical view, is because Ezekiel wrote at the time of the second siege of Jerusalem by Nebuchadnezzar, King of Babylon, (approximately 597 BC), just a surface reading can lead one to conclude that the prophecy of Ezekiel 9 was fulfilled then. But if one looks closely, Ezekiel Chapter 9 is talking about the time of sealing unto salvation or damnation. which clearly relates to the judgement at the end.

Now SOP gives us some insight, 'The Lord reads the heart as an open book. The men who are not connected with God have done many things after the imagination of their own evil hearts. The Lord declares concerning them, "They have turned unto Me their back, and not the face, though I taught them, rising up early and teaching them; yet they have not hearkened to receive instruction." We are amid the perils of the last days, the time will soon come when the prophecy of Ezekiel 9 will be fulfilled; that prophecy should be carefully studied, for it will be fulfilled to the very letter. Study also the tenth chapter which represents the hand of God as at work to bring perfect method and harmonious working into all the operations of his prepared instrumentalities. The eleventh and twelfth chapters also should receive critical, thoughtful attention. Let these prophecies be studied on your knees before God; unless you take up the stumbling-blocks which by your own perverse spirit you have laid in the way of many who have been connected with you, God will turn His face utterly from you and your associates. {1888 1303.1}

Now we have even more...Who are standing in the counsel of God at this time? Is it those who virtually excuse wrongs among the professed people of God and who murmur in their hearts, if not openly, against those who would reprove sin? Is it those who take their stand against them and sympathize with those who commit wrong? No, indeed! Unless they repent, and leave the work of Satan in oppressing those who have the burden of the work and in holding up the hands of sinners in Zion, they will never receive the mark of God's sealing approval. They will fall in the general destruction of the wicked, represented by the work of the five men bearing slaughter weapons. Mark this point with care: Those who receive the pure mark of truth, wrought in them by the power of the Holy Ghost, represented by a mark by the man in linen, are those "that sigh and that cry for all the abominations that be done" in the church. Their love for purity and the honor and glory of God is such, and they have so clear a view of the exceeding sinfulness of sin, that they are represented as being in agony, even sighing and crying. Read the ninth chapter of Ezekiel. {3T 267.1}

The world would not be what it now is if professed believers in Christ were receivers of his divine nature. It is the example of men who claim to believe the truth, but who do not practice the truth, that detracts from the influence of Christianity. They hold the truth as a theory, but unrighteousness surely characterizes their course of action. Many reveal that they are far away from Christ, because they are destitute of Christianity. Please read the ninth and tenth chapters of Ezekiel. Should we not seek to understand the work which God requires us to do? Its results are sacred and awful. If one thread of selfishness is woven into God's service, He is greatly dishonored. Unless those who have knowledge of the truth are sanctified through the truth, their profession counts for nothing, and their condemnation will be proportionate to the light granted them, which they have not honored by walking in the light as Christ is in the light. Truth as it is in Jesus is the creating power of Christ. Those who claim to have advanced light must reveal the influence of that light in their words, their deportment, their voice, their actions, at all times and in all places. {GH, January 1, 1900 par. 4}

In the ninth chapter of Ezekiel is portrayed the fate of the men of responsibility who have not glorified God by faithfulness and integrity. Read this chapter. Notice especially verses four to six: [quoted]. At the appointed time, the Lord God of Israel will do His work most thoroughly. {18MR 183.5)

Study the ninth chapter of Ezekiel. These words will be literally fulfilled; yet the time is passing, and the people are asleep. They refuse to humble their souls and to be converted. Not a great while longer will the Lord bear with the people who have such great and important truths revealed to them, but who refuse to bring these truths into their individual experience. The time is short. God is calling. Will you hear? Will you receive His message? Will you be converted before it is too late? Soon, very soon, every case will be decided for eternity.--Letter 106, 1909. {18MR 236.2}

You can see the problem with just a historical view, as the Spirit of Prophecy clearly applies Ezekiel Chapter 9 to our time, not the time of Ezekiel.

Ezekiel, like Isaiah and Jeremiah wrote for the benefit of people living in their day. Yet their prophecies extend to greater fulfilment in the future.

Daniel and Revelation's prophecies, are different in that they span time, complete with time lines and successive nations, starting from the prophet's time and moving clear down to the restoration of all things, clearly tracking time over earth's history.
Daniel's stories of his life in Babylon, fall into a different category as object lessons or examples of things, but Daniel's actual visions, prophecies, span the centuries, and cannot be broken down to repeating prophecies.

On the other hand, Ezekiel, Isaiah and Jeremiah focus on their day, and then project to various points in the future, with the events in Israel as example of greater things to come.
Ezekiel Nine points first of all to Jerusalem's fate when Babylon devastated it. It can also be projected to 70 AD when again, God withdrew and Israel reaped a terrible devastation, with the temple and city destroyed. And yes, all those destructions were only a limited example for when the whole world will suffer destruction.
