Hold on, page 2 of this chapter says that September 2062 is 5 months after the attack on the quarantine facility, which would mean said attack happened in April (give or take a month due to rounding). Page 3 of ch. 26 implies that AR-15’s big kaboom happened at least 1 month before the aforementioned attack, so the kaboom happened around March (again, give or take a month) 2062, yet page 16 of ch. 25 says that AR-15 made an audio recording on May 8th, 2062.
