I was wondering if maybe the game uses say 19380101 as "Day Zero" and counts numerically up from there, making December 8th, 1941 "Day 1436" (or whatever), and ~everything~ has to match (which it doesn't) in the game, else it goes off by a few days a year (February 29th, April 31st, etc), and then doesn't apply the "upgrades" because of missing "The Date" - even though "the calendar" says otherwise, and when you come back to port after that first patrol after the supposed upgrade date, all is well, because the missing days have passed. In other words, the in-game calendar might say it's January 1, 1945 (Day 2576) when the upgrade should be applied, but the game's "day count" shows it to actually be two weeks earlier (Day 2561), like say December 16, 1944, and hence the upgrade is not applied... ?? maybe? - until those two weeks have passed...
