By unlimited time mode, do you mean the game not stopping after a number of years? Because that's how it already functions. You can play as many years as you like, it doesn't automatically end like in some Harvest Moon games.

Or do you mean no time progression, everything stuck in permanet noon sunlight? Because that might be difficult, since different people seem to do different things depending on the time of day, meaning different events happening as well.
