Here below some reaction what i tried to translate form R.J. van der Spek about this topic.
Although the quotation is correct, I have in all my work exactly the opposite view. historical information must always be prudent used (something that the authors of this Article provides not do so) and the fact that the authors of the diaries were private calls precisely for the reliability. Not that I believe in astrology, certainly not, but the babylonians does and they were very detailed reports of the starry sky and of events on earth. The accuracy of two types of information is also remarkable and also the Babylonian chronicles are a model (certainly to antique concepts) of non-partisan record. That is what my article say. It is precisely the historians like distort reality was once a benevolent story to get their (such as the authors of the watchtower article). The chronology of the new-Babylonian period is certain and there can be no doubt that the first deportation dealt in 597 (under Babylonian chronicles + tens of thousands clay tablets who support this chronology) and the second in 587 or 586 (under biblical chronology). Articles like this type is often written about our section. Writers are not specialists, accept a few dates from the material which appear to defend the argument and ignore the (often overwhelming) evidence that there are objections.
This is what was writen in the WT:
"Even if an eclipse did occur on a certain date, does thismean that the historical information the writer of the tablet assigns to that date is accurate? Not necessarily. Scholar R. J. van der Spek explains: “The compilers were astrologers, not historians.” He describes sections of the tablets that contain historical records as “more or less casual,” and he warns that such historical information must “be usedwith caution.”15"
