to be safe you could TT first with your DS clock so that the game time becomes the time you want it to be (ie. if your game is a year behind, TT your DS a year forward) and start the game with a new character to check that your villagers are still there, and save. then you can change your DS clock back to the right time, and then manually change the time to the right time in game. hopefully that made sense!
Should I do both or one or the other? (Freya wants to move and I'm saying no)
Doing it... Let's see how it turns out... *sets 3DS clock*
Alright...Opening AC and...making a New Character and...hrmm. I started with a new character and the date didn't change... Let me try to reset the 3DS clock again. I didn't really change the date.

Trying it again, this time changing the date and back on the 3DS clock
Okay starting new character and...what? Date not set again? Should I just start with my main character? I mean, I already denied Freya today. Maybe I should just change the 3DS clock to tomorrow this time?
You have to set the 3ds clock forward and open the game, basically setting your 3ds clock forward one day will just move the game forward one day, rather than the in-game date becoming the 3ds date.

and then when you set your 3ds clock back, it'll also set the in game clock back, but you can just change the in game clock to the real date and it won't count as time travel, since your game was last opened on that 'date'
Oh, if you stand still for a minute you can see the date and time.

Well, not a full minute. More like a second, really. XD
