AI Thread Summary
Jack's antique cuckoo clock loses 9 minutes every hour, leading to a significant time discrepancy. Despite this, the clock is observed to be accurate at noon on a Tuesday. The next instance when the clock will be exactly on time again is calculated to be at 4 AM the following Tuesday, which is 80 hours later. This calculation indicates that the clock will align correctly again after a total of 6 days and 16 hours, with some participants estimating it could also be around 8 PM on Friday.
