I did the same thing Olive - I'm tt'ing to catch up as well. I'm Nov. 7 atm - soon to be Nov. 8. The first town, I never TT'd then I had to reset and I want to catch up. I've a second town - the theme town - and I find myself tempted.... must resist....
It was a lot easier to keep the date accurate before I started TT'ing. I just tell myself - what would the villagers say? Hagrid is the mayor of the second, non TT'ing, theme town and he's not suppose to do magic.
I'm nervous about changing my clock because I don't want to lose anyone or mess up the built in steep counter the 3DS has, because of this my clock is an hour fast between November and March because I don't even change the clock for daylight savings time because I'm paranoid something bad would happen if I change the clock even once.
