587 BCE as year 18 of Nebuchadnezzar is part of the overall distortion of the NB Period. It was distorted by 57 years during his reign by the Persians. The VAT4956 tries to hide some secret references from the original timeline for year 37 of Nebuchadnezzar II, thus those of us who keep up with the recent research can recover the original dates for at least the rule of Neb-II using this document. Year 37 originally occurred in 511 BCE.
The significance of that is that this dates year 23 to 525 BCE which after you add 70 years of exile of the last deportees you get 455 BCE for the 1st of Cyrus, which few will argue is the implied fulfillment of the "70 weeks" which begin with the "word going forth to rebuild Jerusalem." So some of us use the VAT4956 to move beyond the false date of 587 BCE for year 18 of Neb-II. At this point though, because of the VAT4956, pretending 587 BCE is a viable date in ancient history for year 18 of Neb-II is just a matter of incompetence. In the meantime, the corrected dates found in the VAt4956 totally agree with the Bible's timeline for the NB Period! It's quite amazing!
