The in game year is 3300, but the game matches the calender date (i.e. in game is 23rd Sept, just a fair few years in advance).
2014 and 3300 are not leap years.
2015 and 3301 are not leap years.
2016 is a leap year, 3302 is not a leap year.
So, Feb 29 2016 will be what date in game 3302?
Then what about March 1st 2016....
Hope Frontier have given thought to the DateTime calculations! since if they are just using DateTime.Now.AddYears(1286), there might be an issue (in a few years!)
