It's a known bug with the Year 2000 code. The cure is to set the calendar to 28 years ago (28 is due to the day of week and leap year sequences repeating every 28 years), and re-enabling the cloak-calendar chip. If your ACC is still running in 2027 you would set it to 56 years ago (as far as ACC goes it's always 1971 to 1999).
