The only certain time of Revelation written is John on Patmos.This link is good showing how other books in the New Testament refer to revelation showing that they were written after revelation or at the same time
Christ prophecying of the same things through different apostles, doesn't date their writing before nor after the other.
Of course, we do know that the prophets all wrote of the Lord's return and Millennium gvt on earth, before any apostle.
Enoch prophecied the day of the Lord's return before Jesus, Paul, Peter, Jude, and John. That is the manner of His return, not the date.
