It works...even my automatic date reset doesn't reset while playing & cheating...If it doesn't work for u try this method instead:
Legends- -Method Title >Example *Note
-Play Sims
-Go to Settings 'Date & Time' Press the 'Hour'
>(Example: 12:00)
-Click it then just press the 'AM/PM' arrows.
> Example: 12:00 PM change it into AM then...
*(make sure always 12:00 AM/PM)
-Change your Month or Date
>(Example: 12/12/12)
*(click once 'Increase Day' Arrow. If you have reached '30th day or 31st day of the month' just change to the next month)
> Example: 12/30/12 >>> 1/1/13 and then..
- Go back to your sims
Note: This Cheat will help you level up, Earn, and much more! (This cheat is usable while using 'Automatic Reset Date')
