Trium,
The list I posted above starting with 1150, 800, 50, etc is now over 100 numbers long and it doesn't repeat itself yet.
I have run some other tests. I deleted the house that I was using for this clock and build a new tent in the same spot about 3 years later than the first house. It is now June 3. I checked and re-checked and the new house doesn't join the clock at any point known so far. It's numbers were completely new.
Then I though lets build another tent in June 3 on same spot. This third tent repeated the numbers of the earlier June 3 tent. Then a July 3 tent repeated the same numbers like the two June 3 tents but started one number later.
In short, I drew two conclusions:
1. The spot the house is build (the northern tile, and it doesn't matter whether it is 1x1 or 2x2 that have the same northern tile) determines the clock the house is going to use.
2. The moment the immigrant arrives in game time (regardless when you build the vacant lot) determines at what point the house is going to join the clock. The calender month doesn't matter. The clock is already running for the terrain spot. If the immigrant arrives in late June 3 it will join the clock at some point.
If I delay the immigrants arrival by building some obstacles and he arrives early July but is still able to catch the same interval then he too will join the clock as the immigrant who arrived in late June.
If I delay the immigrants arrival even further, he will miss the first interval and join the clock on the next interval.
Because I can delete all houses and then rebuild a house at the same month at the same spot and it will use the intervals that I found earlier, that means the clock for that terrain tile is saved somewhere in the sav file.
I don't know how the game saves it. I will post the numbers and maybe you can find where these come from. Are they generated on the fly by multiplying game clock and a set of numbers that change according the terrain? Are they pulled from the long list that is written somewhere and the terrain has just a reference to which list it is using? I don't know that part.
