I've time traveled in the past to get villagers out (for bad house placement rather than anything about the particular villager) once I started actually planning my town layout. Now that that's done, I just decided to do it again to relive the past -- I put down the game right before my birthday at the end of summer and just picked it up again a week ago (when I bought my daughter a copy). I realized that, for the second year in a row, I'd missed most of autumn and all of winter. (I don't know why spring makes me pick up this game again after a break.) So I traveled back to October but plan to play day-by-day until at least New Years passes, to see all that I missed.
