What source mentions 2345 if I may ask? There is certainly convincing evidence to suggest that they aren't chronological however I still feel that was the original intention (sort of like a stamp put for every new ship launched in order of completion, which makes the most sense really) but then the production staff kept changing things to keep the story going. I don't think when Night Terrors came out anyone had any idea the Dominion War would be a reality only a few years forward. BTW I did read your Chronological Timeline which I (mostly) agreed on. Good research there!
