The concept of"TIME" is a very interesting topic, but I don't think it can accurately be comprehended.
The book that might be described or summing up and EXPLAINING REALITY (the bible) can be thought of as describing 2 TIMES/EPOCHS.
Jesus was sent to earth "as a plan for THE FULNESS OF TIME" (yes, the END OF TIME). He ended the age of time,....and also began the age of eternity).....He is the ETERNAL SABBATH OF ETERNAL GOD......
Deuteronomy 33:27 .....ETERNAL GOD...
Jesus "THE CHRIST" the lion of Judah became IMMANUEL the LAMB OF GOD (that's what the book of Revelation is all about ....(the lion lays down with the lamb).
GOD transcends TIME (to us humans, TIME is an IMAGINARY? and SUPERNATURAL concept...I THINK).....or is it a psychological manifestation of our FINITE minds????

Now and then in my life, I wondered about Revelations 8:12 (about the "ONE THIRD" time differential) and it seems to be due to the calendars and the volcanic winter disasters of 536 a.d.......
…the time differential (“one third”) of Revelation 8:12 is likely the switch to the GREGORIAN calendar from the JULIAN…..(more extensive investigation is required by historians and chronologists).
