Julian of Toledo
The Jewish Encyclopedia claims that Julian of Toledo accused the Jews of falsifying their chronology in connection with an argument that the Messiah was to arrive in the “sixth age”. - quoted here - Reference note: Singer, Isidore and Adler, Cyrus et al., eds.

Jacob of Edessa (AD 700)
Yet another ancient author mentioned by Smith, Jacob of Edessa (AD 640–708), claimed the Jews falsified the Hebrew numbers to disqualify Jesus from being the Messiah under the eschatological scheme of chiliasm.9 But Jacob of Edessa simply asserts this without any evidence to substantiate it, and it is just as late a statement as that of Julian of Toledo (seventh century). - Quoted here - Note 1: Chiliasm is derived from the Greek word for ‘thousand’. It is the belief that the world will last for 7,000 years, with each thousand years corresponding to one of the days of Creation Week, and the seventh day corresponding to a future Millennium. It was a common eschatological scheme for both Jews and Christians, though there are different forms. - Note 2: ter Haar Romeny, B.

Ephraem of Syria
Answers in Genesis Ephraem of Syria is the first known ancient source to explicitly argue that the Jewish rabbis of the second century AD deflated the primeval chronology by ca. 1300 years in their Hebrew MSS for the purpose of discrediting Jesus as the Christ: “The Jews have subtracted 600 years [in Genesis 5] from the generations of Adam, Seth, etc., in order that their own books might not convict them concerning the coming of CHRIST: he having been predicted to appear for the deliverance of mankind after 5500 years.” Cited in: Hales (1830, 278). For additional citations of Ephraem’s claims, see: Assemani (1719), Wacholder (1974, 99), and Anstey (1913, 46). Ephraem was one of many ancient authors who claimed that the rabbis deliberately reduced the primeval chronology for messianic reasons.
Wikipedia: Cave of Treasures The Cave of Treasures, sometimes referred to simply as The Treasure, is a book of the New Testament apocrypha. It is believed to have been written in the sixth century or later. This text is attributed to Ephrem Syrus, who was born at Nisibis soon after AD 306 and died in 373, but it is now generally believed that its current form is 6th century or newer... He saw that the manuscript contained the history of 5,500 years, from the creation of Adam to the birth of Christ, and that it was based upon the Scriptures. He says that fables are found in it everywhere, especially concerning the antediluvian Patriarchs, and the genealogy of Christ and His Mother.
sacred-texts.com: cave of treasures The writer of the "Book of Adam and Eve" meant the two sections to form a complete work. The first shows how Adam fell, and the second tells us how God fulfilled the promise which He made to Adam more than once, that after five and a half weeks, i.e. 5,500 years, He would send a Redeemer into the world who would save both Adam and his descendants from the destruction which his sin in Paradise had incurred... He read the MS. carefully and saw that it contained the history of a period of 5,500 years, i.e. from the creation of Adam to the birth of Christ, and that it was a historical chronicle based upon the Scriptures. He says that fables are found in it everywhere, and especially in that part of it which treats of the antediluvian Patriarchs, and the genealogy of Christ and His Mother... When Adam and Eve left Paradise they went into a strange land, and were terrified at the stones and sand which they saw before them, and became like dead folk. Then God sent His Word to them, and He told them that after five and a half weeks, i.e. 5,500 years, He would come in the flesh and save man. He had already made them this promise in Paradise, when they stood by the tree of forbidden fruit.

This accords with the promise to Seth of the coming of a saviour after 5,500 years found in certain manuscripts of the LATIN LIFE.
Latin life presumably refers to apocryphal Latin_Life_of_Adam_and_Eve, but I see no reference to it there. It does say only certain manuscripts of it contain it though.
A rebuttal from creation.com
When examining Smith’s work, a problem with his sources comes up extremely early (i.e. the third sentence of his introductory paragraph in the ARJ paper). Concerning the date differences between the MT and LXX, he says that “Eusebius (AD 260–340) is the first known author to explicitly cite and discuss the divergences, followed by Ephraem of Syria (AD 306–373)…” (ARJ, p. 169). That sounds innocuous enough, but in the note for that statement, he says, “Ephraem of Syria is the first known ancient source to explicitly argue that the Jewish rabbis of the second century AD deflated the primeval chronology by ca. 1300 years in their Hebrew MSS for the purpose of discrediting Jesus as the Christ: ‘The Jews have subtracted 600 years [in Genesis 5] from the generations of Adam, Seth, etc., in order that their own books might not convict them concerning the coming of CHRIST: he having been predicted to appear for the deliverance of mankind after 5500 years.’ Cited in: Hales (1830, 278). For additional citations of Ephraem’s claims, see: Assemani (1719), Wacholder (1974, 99), and Anstey (1913, 46).” (ARJ, note 3, all punctuation and italics in original). But Smith did not cite an original source for the Ephraem quote. As good students of biblical scholarship, we should trace everything back to the original if possible. But after repeated attempts, we were not able to authenticate this quote by Ephraem the Syrian, nor to trace it further back than Hales (who Smith referenced in the quote above). This is a critical piece of evidence for those that support the LXX’s authority. [...] Yet, Ephraem the Syrian wrote a commentary on Genesis. One might expect to be able to ascertain his specific interest in chronology, and what text he was drawing from, by consulting that work. In his comment on Genesis 5, Ephraem says, “Then after he [Moses] had finished writing about the tribes of the descendants of Cain and had completed the story of the words of Lamech to his wives, [Moses] turned to record the generations of the house of Seth, beginning from Adam, saying that when Adam had lived one hundred thirty years, he begot a son in his own likeness according to his image.”3 But the LXX has “230” years for Adam’s age when Seth was born. Ephraem also says that Noah was 500 when he bore his sons, about which all traditions agree. There is another intriguing statement in Ephraem’s commentary that conclusively shows he was using a MT-like chronology. Regarding Melchizedek, he says: “This Melchizedek is Shem … Shem lived not only to the time of Abraham, as Scripture says, but even to [the time of] Jacob and Esau, the grandsons of Abraham.”4 This statement is true if we use the MT chronology, but is impossible with an LXX-like chronology, for with the extended ages of paternity in the LXX chronology of Genesis 11, Shem would have been long since dead. How can anyone claim that Ephraem viewed the MT chronology as a corruption by unbelieving Jews, when he was more than happy to use it in multiple places in his Genesis commentary? Thus, we have already uncovered multiple problems: Smith’s quote above claims to be from Ephraem the Syrian, but it is not yet traceable back to anything Ephraem the Syrian actually wrote. We could not authenticate it and Smith provides no way for anyone else to effectively do so. This is sloppy on his part. Furthermore, Ephraem’s extant work includes a commentary on Genesis in which he uses the Masoretic text! Unlike Smith, we cited a primary source to make it easy for anyone to find. Why did Smith not reference Ephraem’s Genesis commentary? Was he unaware that it existed? Update (4 October 2018): A helpful reader was able to provide us with the Wacholder reference. This allowed us to pinpoint the specific location of the quote within Assemani's Biblioteca Orientalis. Assemani traces the quote to Ephraem’s Exposition of Genesis and Exodus, which as we showed uses an MT chronology and lacks any such statement by Ephraem. We are unable to trace the quote further than Assemani. In any case, it is clear that an entire line of scholars, from the 18th through the early 20th centuries, transmitted an apparently fake quote. This has been cited by numerous modern LXX advocates who also did not bother to authenticate it. We have attempted exactly that, and not only were we unable to do so, but we found strong evidence that Ephraem believed no such thing.
Ephraem of Syria is the first known ancient source to explicitly argue that the Jewish rabbis of the second century AD deflated the primeval chronology by ca. 1300 years in their Hebrew MSS for the purpose of discrediting Jesus as the Christ: “The Jews have subtracted 600 years [in Genesis 5] from the generations of Adam, Seth, etc., in order that their own books might not convict them concerning the coming of CHRIST: he having been predicted to appear for the deliverance of mankind after 5500 years.” Cited in: Hales (1830, 278).

Eusebius (AD 260–340) is the first known author to explicitly cite and discuss the divergences, followed by Ephraem of Syria (AD 306–373),3, 4 Jerome (AD 340–420), Julian of Toledo (AD 642–690), Jacob of Edessa (AD 640–708), Byzantine chronologist George Syncellus (d. AD 810), and Armenian annalist Bar Hebraeus (AD 1226–1286),14 just to name a few.4
Each of these ancient authors (save Jerome) argued that the Jewish rabbis in the second century AD deflated the primeval chronology by ca. 1300 years in their Hebrew manuscripts to discredit Jesus as the Messiah. Chronological speculations and calculations about the time of the messiah’s arrival (messianic chronology) were widespread in Second Temple Judaism. Messianic chronologies were usually associated with the Days of Creation, with each day representing 1000 years of history. In some schemes, the messiah would arrive in the 6th millennium (5000–5999 AM), and usher in the kingdom in the 7th millennium (6000 AM) (Beckwith 1996). Many Jews believed the Messiah would arrive in/around the year 4000 AM (Silver 1927, 6, 16). See also the rabbinic Babylonian Talmud: Abodah Zarah 9a, Sanhedrin 97b. Reducing the primeval chronology as presently found in the MT places Jesus’ life outside the time of the coming of the Messiah. The rabbinic world chronology in The Seder Olam Rabbah (ca. AD 150), which is derived from the MT, places Creation at 3761 BC, and the arrival of the Messiah about AD 240, eliminating Jesus from messianic consideration. The Seder Olam significantly deflates post-Exilic chronology as well, and reinterprets Daniel 9 to associate it with the destruction of the Temple instead of Jesus Christ. It was written by the very same rabbis who, we argue, deflated the proto-MT’s numbers, and who had complete control over the Hebrew manuscripts that survived the destruction of the Temple. This ancient and historically-grounded claim has been recently reintroduced to conservative OT scholarship by Sexton (2015, 210–218) who documents numerous post-Reformation Christian scholars who also made this argument, favoring the priority of the LXX in Genesis 5 and 11. See also: Sexton and Smith Jr. (2016). The arguments from this article favoring the LXX’s primeval chronology were recently surveyed in Thomas (2017, 125). Eusebius does not attribute the motive to messianic chronology and discrediting Jesus, rather, their purpose was to encourage their contemporaries to lower their age of marrying. This motivation is inadequate and is not supported by any historical evidence (Chronicle 25:10) . However, Eusebius’ explanation confirms the widespread belief that the rabbis altered the text.
Julius Africanus (ca. AD 221/222) Julius Africanus (AD 170–240) wrote his Chronographiae while living in Israel, and was an advocate of the LXX chronology. Fragment 16a details the Septuagint’s antediluvian begetting ages, listing Methuselah’s as 187 years old. In 16b, Africanus provides a pre-Flood summation of 2262 years, which places Methuselah’s death six years before the Flood, consistent with the 187 figure (Wallraff, Roberto, and Pinggera 2007, 27–29, 35).
Fragment 15 reads: “. . . and from their remaining Hebrew histories, they [the Jews] have handed down a period of 5500 years up to the advent of the Word of salvation [Christ] . . .” (Wallraff, Roberto, and Pinggera 2007, 25). Africanus resided in Israel most of his life, and had knowledge of Greek, Latin, and Hebrew. He even refers to Hebrew as “our” way of speaking (Wallraff, Roberto, and Pinggera 2007, xv–xvi). Thus, Africanus would have been able to compare manuscripts of the LXX to those available to him in Hebrew. It is interesting that Africanus never mentions the numerical divergences between the (proto) MT and LXX in Genesis 5 and 11. Perhaps this is evidence that his particular Hebrew texts contained the higher begetting ages.
https://en.wikipedia.org/wiki/Year_6000 According to classical Jewish sources, the Hebrew year 6000 (from sunset of 29 September 2239 until nightfall of 16 September 2240 on the Gregorian calendar) marks the latest time for the initiation of the Messianic Age. The Talmud, Midrash, and the Kabbalistic work, the Zohar, state that the 'deadline' by which the Messiah must appear is 6,000 years from creation. According to tradition, the Hebrew calendar started at the time of Creation, placed at 3761 BCE. The current (2019/2020) Hebrew year is 5780.

The Jewish sage Rabbi Akiva (alternatively Akiba) indulged the possibility that Simon Bar Kosiba (Bar Kokhba) could be the Jewish Messiah, and gave him the surname “Bar Kokhba” meaning “son of a star” in the Aramaic language, from the Star Prophecy verse from Numbers 24:17: “There shall come a star out of Jacob”
At the time, Jewish Christians were still a minor sect of Judaism, and most historians believe that it was this messianic claim in favor of Bar Kokhba alienated many of them, who believed that the true Messiah was Yehshua, and sharply deepened the schism between Jews and messianic Jews
The struggle lasted for three years before the revolt was brutally crushed in the summer of 135 CE. After losing Jerusalem, Bar Kokhba and the remnants of his army withdrew to the fortress of Betar, which also subsequently came under siege. The Jerusalem Talmud relates that the numbers slain were enormous, that the Romans “went on killing until their horses were submerged in blood to their nostrils”. The Talmud also relates that for seventeen years the Romans did not allow the Jews to bury their dead in Betar.
Outcome of the war According to Cassius Dio, 580,000 Jews were killed, and 50 fortified towns and 985 villages razed.
Hadrian attempted to root out Judaism, which he saw as the cause of continuous rebellions. He prohibited the Torah law and the Hebrew calendar, and executed Judaic scholars. The sacred scroll was ceremonially burned on the Temple Mount. At the former Temple sanctuary, he installed two statues, one of Jupiter, another of himself. In an attempt to erase any memory of Judea or Ancient Israel, he wiped the name off the map and replaced it with Syria Palaestina (after the Philistines, the ancient enemies of the Jews) supplanting earlier terms, such as “Judaea” and Israel. Similarly, he re-established Jerusalem but now as the Roman pagan polis of Aelia Capitolina, and Jews were forbidden from entering it, except on the day of Tisha B’Av.
According to a Rabbinic midrash (the Ten Martyrs), in addition to Bar Kokhba the Romans executed ten leading members of the Sanhedrin: the high priest, R. Ishmael; the president of the Sanhedrin, R. Shimon ben Gamaliel; R. Akiba; R. Hanania ben Teradion; the interpreter of the Sanhedrin, R. Huspith; R. Eliezer ben Shamua; R. Hanina ben Hakinai; the secretary of the Sanhedrin, R. Yeshevav; R. Yehuda ben Dama; and R. Yehuda ben Baba. The Rabbinic account describes agonizing tortures: R. Akiba was flayed, R. Ishmael had the skin of his head pulled off slowly, and R. Hanania was burned at a stake, with wet wool held by a Torah scroll wrapped around his body to prolong his death.
They note that, unlike the aftermath of the First Jewish-Roman War chronicled by Josephus, the majority of the Jewish population of Judea was either killed, exiled, or sold into slavery after the Bar-Kokhba Revolt, and Jewish religious and political authority was suppressed far more brutally. After the revolt the Jewish religious center shifted to the Babylonian Jewish community and its scholars. Judea would not be a center of Jewish religious, cultural, or political life again until the modern era, though Jews continued to live there and important religious developments still occurred there. In Galilee, the Jerusalem Talmud was compiled in the 2nd–4th centuries. Eventually, Safed became known as a center of Jewish learning, especially Kabbalah in the 15th century. 
The disastrous end of the revolt also occasioned major changes in Jewish religious thought. Messianism was abstracted and spiritualized, and rabbinical political thought became deeply cautious and conservative. The Talmud, for instance, refers to Bar-Kokhba as “Ben-Kusiba”, a derogatory term used to indicate that he was a false Messiah. The deeply ambivalent rabbinical position regarding Messianism, as expressed most famously in the Rambam’s (also known as Maimonides) “Epistle to Yemen”, would seem to have its origins in the attempt to deal with the trauma of a failed Messianic uprising
Last week we shared with you the history of events around the Bar Kokhba Revolt. We wanted you to understand the events of the time and how Judah wanted Simon to be the Messiah. Mostly at the prompting of Rabbi Akiva
Bar Kochba’s supporters read into the Second Revolt a fulfillment of the prophecy in Daniel, 9:24-27, which states that the messiah would come AFTER 483 weeks (incorrectly interpreted to mean 483 years), i.e. in the 484th year of the building of the second Temple. In their calculations, the destruction of Jerusalem (70CE) took place in the 421st year of this era. 2/7 Since the 421st year of this period equals 70 CE, the rabbis began this era in 351 BCE (see chart B). In reality, this construction is impossible. The era starts when the command went forth to build the second Temple; yet the first stages of the second Temple were already completed in the sixth year of King Darius of Persia (515 BCE). Therefore, the early construction of the second Temple was actually completed some 164 years before the rabbis calculated that the work to build it had started. Neither can the rabbinical understanding be a reference to a later building phase, for the second Temple was not enlarged until the eighteenth year of King Herod (20/19 BCE)
The clear intent of the contrived chronology from the period is to prove that Bar Kochba was the promised messiah. The 484th year of this era, the year in which the messiah was to appear, becomes 133/134 CE. This date, therefore, proves that the Second Revolt would have actually begun in 133 CE not 132 CE (133 CE being the year in which the messiah’s appearance was expected). Other contemporary rabbis and later rabbis dismissed the Bar Kochba messianic attachment to the chronology but inaccurately continued use of it as if it was a factual framework for the past
The Bar Kochba Chronology Let us first examine in more depth the origin of the Bar Kochba Chronology. A major error of the advocates of system “B”, “C”, and “D” has been their failure to take into account the source of the chronology used by the authors of the Seder Olam and other Talmudic works. This chronology originated from the supporters of Bar Kochba who read into the Bar Kochba revolt the prophecy of Daniel, 9;24-27, which foretold of the appearance of the messiah. First, it can be no mere coincidence that the year 133 CE, year 16 of Hadrian, is the 484th year of the era of building the second Temple – the year 351 BCE being the date determined by the rabbis as the time when the building of the second Temple began. Why did these rabbis calculate a date so far from the truth (i.e. over 164 years) if it had not arisen for some religious and political purpose? The very fact that the chronology agreed upon by the rabbis from the time of Rabbi Jose (about 160 CE) was based upon the prophecy of Daniel, 9:24-27 – and then finding that his chronology fulfills the messianic expectation at the time of Bar Kochba’s insurrection – clearly indicates its original source and intent. In fact, Rabbi Jose, who wrote the Seder Olam (the text upon which Talmudic chronology is built) only about 25 years after the end of that revolt, also 3/7 lived at the time of the Second Revolt. Nevertheless, he was not the originator of the chronology but only its transmitter.
Rabbi Yahanan, who lived in the next century after Jose, and the Babylonian Talmudic works Yebamot (82b) and Niddah (46b) report that Rabbi Jose “taught” Seder Olam. Rabbi Jose (Yose) is himself cited nine times in the Seder Olam, while other Rabbis, all of them Tannaim, appear altogether ten times. Milikowsky concludes from this evidence.
Jerome (early fifth century CE) gives the view of some of the Jewish scholars in his day that the last septennium of Daniel, 9:27, is to be divided between the siege of Vespasian and the siege of Hadrian. That is, three and one half years are to be allotted to each event. It is clear from Jerome that the underlying idea of some of the Jews in the Talmudic period was to apply the calculations of the end time prophecy of Daniel to the two destructions of Jerusalem, which occurred during the First and Second Revolts.
