The time jump is necessitated by early references to the previous novel ("three weeks later") and later references to the TOS episode "Arena", which Precipice firmly places in the November/December region.
There is some debate over when exactly the jump occurs, I have opted for it to occur early in the novel, others (I believe @Idran?) only place a few chapters in November.
Well, it turns out that Precipice starts on January 3, 2267, five weeks after the verdict of Commodore Reyes' court-martial; fortunately for me, Precipice has specific dates which makes cataloging it so much easier than its predecessors.
Speaking of, when does Almost Tomorrow (Declassified #1) take place (other than early 2265)? It seemed like Reyes, Lt. Cmdr. Cannella, Lt. Dunbar, Lt. Cmdr. T'Prynn, and a few others, including the station's diplomatic staff, had been on the station for about a month, Capt. Desai arrived the day before, Cmdr. Cooper was two weeks out, and officers such as Lt. Moyer and then-Ens. Greenfield (Cdre. Reyes' yeoman) haven't been assigned yet.
