Here we find quotes from early christian leaders as to authorship and dates.

Found in the article is the followoing:
"The early church attributed authorship to the apostle John. Justin Martyr (100-165 A.D.) quotes John the Apostle that Jesus Christ would dwell in Jerusalem one thousand years.[1] Irenaeus (120-200 A.D.) is quoted in every chapter of Revelation. Tertullian (155-220 A.D.) also quotes from almost every chapter of Revelation and attributes John the Apostle as author. Hippolytus (170-235 A.D.) also attributed Revelation to John, he quotes Revelation chapter 17 and 18 a great deal. Clement of Alexandria ( 150-211 A.D.) and Origen (185-254 A.D.) also attribute John the Apostle as the author of Revelation. Ignatius (30-108 A.D.) writes regarding John the Apostle,
And why such facts as the following: Peter was crucified; Paul and James were slain
with the sword; John was banished to Patmos; Stephen was stoned to death by the Jews who killed the Lord? But, [in truth,] none of these sufferings were in vain; for the Lord was really crucified by the ungodly.[2]
The evidence against John the Apostle being the author is minimal, largely based on grammatical and writing style differences with the John’s Gospel.
When was the book of Revelation written?
The other issue regarding Revelation is the date of the book. External tradition places the time of Revelation to the reign of Domitian (A.D. 81-96), brother of Titus, son of Vespation. Clement of Alexandria reports John returned to Ephesus after the death of Domitian, referred to as the “tyrant”.
the Apostle John. For when, on the tyrant’s death, he returned to Ephesus from the isle of Patmos, he went away, being invited, to the contiguous territories of the nations, here to appoint bishops, there to set in order whole Churches, there to ordain such as were marked out by the Spirit.[3]
Eusebius (A.D. 300-340) the father of church history writes in his Ecclesiastical History about the connection between John the Apostle and Domitian.
IT is said that in this persecution the apostle and evangelist John, who was still alive, was condemned to dwell on the island of Patmos in consequence of his testimony to the divine word. Irenaeus, in the fifth book of his work Against Heresies, where he discusses the number of the name of Antichrist which is given in the so-called Apocalypse of John, speaks as follows concerning him: a “If it were necessary for his name to be proclaimed openly at the present time, it would have been declared by him who saw the revelation. For it was seen not long ago, but almost in our own generation, at the end of the reign of Domitian.”[4]"
It appears the 95 to 96 A.D. writiting of the book of revelation is accurate if you believe the writings of these men who live in the 100 and 200 A.D. time period.
[1] Justin Martyr [2] Ignatius [3] is from Clement of Alexandria,[4] is Eusabias.
