Depending on one's interpretation of the Scriptures (e.g., whether Michael = Jesus Christ), there are different lines of arguments one can follow. From the following one can pick out a few "witnesses":
So when would the “[the] end time” (= time of [the] end) start? If one examines the course of modern history, one notices that one date, the year 1914, stands out. The period during which the visions of Revelation will unfold is called “the Lord’s day” (cf. Rev. 1:10). This period will start in 1914. How can we know for sure?
The first line of evidence is circumstantial. Revelation 12 indicates the birth of the Messianic Kingdom (Rev. 12:1-5). Jesus Christ would be enthroned in heaven as Jehovah’s appointed king (Dan. 7:13, 14, 26, 27). Under his heavenly name Michael, his first task would be to evict Satan (Rev. 12:9, 10; cf. Dan. 12:1, 2).
The fourth beast, Rome, would eventually sprout an eleventh horn, the British Empire. It would humiliate three horns, Spain, France, and the Netherlands. At the beginning of the end time, this horn would grow large, turning into the Anglo-American world power, later called King of the South (cf. Dan. 7:7, 8, 17, 19-21, 23; 11:27-29). During this time the life of the rest of the political beasts (Babylon = Iraq; Medo-Persia = Iran; Greece) would be prolonged (cf. Dan. 7:4-6, 12; Rev. 17:12, 13).
Those nations under the King of the North and South would become enmeshed in vicious wars over supremacy (cf. Ps. 2:1, 2; 110:1, 2). The prophet Isaiah (19:2) predicted that Jehovah “will goad Egyptians against Egyptians, and they will certainly war each one against his brother, and each one against his companion, city against city, kingdom against kingdom” (cf. Matt. 24:7, 8; Mark 13:8; Luk. 21:10).
Within a biblical context, Egypt could be viewed as the first world power (cf. Rev. 17:10). But here the term “Egyptian” would take on a wider meaning. These kingdoms would fight for the right to rule, in other words for “the scepter of Egypt” (cf. Zech. 10:8-12). The significance of the term “the land of Egypt” will be discussed later.
To confirm the above, we are introduced to four horseman of the Apocalypse. The first horseman, a conquering Christ (cf. Dan. 12:1; Rev. 12:7; 19:11-16), is followed by three horsemen, accurately portraying the conditions on earth since the outbreak of the First World War (cf. Rev. 6:1-3).

The second line of evidence, pointing to 1914 as the beginning of “[the] end time”, is chronological. This is somewhat controversial, because secular chronology, dealing with the Babylonian monarchy, differs from Bible chronology. The Nabonidus Harran Stele and Ptolemy’s Canon, amongst others, point to 587/586 BCE as the date of the first destruction of Jerusalem. Bible chronology pinpoints the date as 607 BCE. The seven times of Dan. 4 (7 x 360 = 2520 years), otherwise known as the Gentile Times, bring one to 1914 CE (Num. 14:34; Ez. 4:6; Dan. 4:23; Luk. 21:24).
