Given the game's geology, how should the weather be changing?
Should there be seasons? If so, why?
Should mountain peaks be colder? Is yes, why?
Should there be rain storms? How would they form?
As for time of day and date, should the date be pegged to the US calendar or Italian? Should leap year be followed? Should daylight savings be observed? Do these things have relevance in the game? Are such cycles geologically possible given the settings?
