The print copies were edited to remove some time references, yes, but it's because the chronology was compressed, not extended. While some specific timespan references were removed, stardates were edited from early-2377 to late-2376 so that they could place Wounds within the Worlds of DS9 series at the end of 2376. Which is absolutely ridiculous pacing.
And as for the reference in Grand Designs, I'm not sure if it survived to the print version, but in the eBook version it's in Chapter 2, fourth paragraph down.
Also, minor irrelevant correction: Gomez isn't chief engineer, she's first officer and commander of the SCE detachment. Conlon's the chief engineer.
As far as Grand Designs goes, I don't have that one. My latest book is (going from Voyager's #) is Pocket Full Of Lies (Jan. 2016). This is for another thread...
Onto the Stardates here, I've noticed that the novels are actually a few years behind in terms of the 24th C timeline. Let me expand:
There are sites out there with varying calculators out there for Stardate calculation. At the end of the first season of TNG (The Neutral Zone) on May 16, 1988, the O.E.C. date was set as the year 2364.
I tend to follow Mike Okuda's line of thinking in that a year is 1000 stardates, with 1/1 at 00:00:00 as the xx000.0 point. Each second of the day is equal to .0000317 stardates. Dragging the calculation out, for each 1.0 Stardate, there are 31,945 seconds (or 8:52:25 in h:m:s format). A stardate of 41986.0 would put the date as December 26th, 2364 at 21:21:35 as the date and time of the log entry for The Neutral Zone.
That is 376 years, 7 months and 10 days of difference. Disregarding the months and days at this point, I have the year pegged at 2393, not 2386/7 as the novels seem to be at this point. This should put the SD at 70xxx and not 63 or 64xxx.x. As of today, the SD should be 70167.5.
