If you’re using an iPhone or iPad introduced in 2012 or earlier, you should check your device for an iOS update if you want it to keep reporting the correct time, date, and location.
Apple is pushing a software update to a selection of older iOS phones and tablets to fix an issue affecting global GPS. The problem is known as the Week Number Rollover issue, and its caused by GPS systems recording the passage of weeks as a 10-bit figure. This means that when they hit week 1,024 (just under 20 years) their count resets. As a consequence, some older hardware is thrown off course — both figuratively and literally. It’s similar to the Millennium/Y2K bug, which was also caused by the reset of a date count.
