No nitpicker, I find it rather odd that you dismiss quite readily the nine-date stamps in Daniel as of no significance in establishing not just it's setting but its date of composition and the fact that it is a book of prophecy. Whereas when it comes to a matter of chronology and history in establishing the time and length of the siege of Jerusalem you appeal to Ezekiel who similar to Daniel was a prophet and his book as like Daniel is a prophecy.
It truly is laughable that you imagine that referring to the date of an event is a 'date stamp' that necessarily establishes the date of writing. Surely you can't really be that stupid. Although, given that your related 'explanation' is that the book must be magical, you probably are. Neither Ezekiel nor Daniel are magical books, but it is indeed true that statements in Ezekiel help confirm the length of the siege on Jerusalem prior to its destruction (though the verses in Ezekiel are not required to properly calculate the duration when the dating systems are correctly understood).
Further, Ezekiel only has one regnal date stamp and eleven time stamps, two of which you quote in support of your argument namely Ezek. 24:1; 33:21 so your position is rather false and inconsistent. What then is your date of composition of Ezekiel ? Do you regard this book as prophetic?
Oh, you're still prattling about 'date stamps'. I wasn't talking about the date of composition of Ezekiel at all. I simply noted that the JW dogma is also wrong about the length of the siege, as shown by Ezekiel (in addition to other relevant facts about the dating systems used). As it happens, Ezekiel was most likely completed some time between 571 BCE and 568 BCE inclusive (since the author amends the text to account for the failure to capture Tyre but not for the failure of the 'prophecy' about 40 years for Egypt), though revisions could have been made after that.
