Alas, nay! Nein! Kein! Nicht! No siree Bob! These are in the game itself, as released to the general public, from the first release, through v1.5. As mentioned before, you won't usually encounter any issues. Look in the "Drive:\
Game \ Data\ Submarine \
AnyBoat \
AnyBoat.upc" files, and you'll see these. They're throughout the game any place dates are used, including all of the UPCData folders & files. The game most likely does not use "dates" per se, but rather 'counts' the days from the beginning, and converts that data to calculate a given date when needed. It seems to count fine, and will usually display "Messages.txt" when it's supposed to, but besides overlaps of dates for equipment and flotilla starts, what happens in the game enigine? Only the tracers know...
