This is the comment that is on fire numerous forums on iPhone, and it’s true. What is not yet known why change the date that particular day generates a critical error, but there is a hypothesis.
It all started in that infamous nest of trolls called 4chan, where a joke saying that if you changed the current date 1 1 1970 activava an Easter Egg showing an interface with the look spread Macintosh Classic.
Change thus far no active non Easter egg. What it does is let the phone completely useless that refuses to boot. Try to reset it by force or by iTunes does not work. The only alternatives are to let the battery completely runs out to restart date, apply a firmware update, or take the terminal to an Apple Store and hold the smiling glances as you restore the iPhone. This video of Tom Scott visually explains the error.
The bug is more than proven, but what is not so much the cause. The main hypothesis is a problem with the figures used by the operating system to know what date it is. iOS is based on Unix and Unix does not measure time as we do, but the date and time translates to a numerical value corresponding to the number of seconds since a specific date. That date is precisely 00:00:00 September 1, 1970, whose value is zero.
The problem is not the specific date, but earlier. To show, for example, notification or email before that date, the operating system must use negative numbers. Unix temporary tables contemplate that possibility until 1904. However, it seems that Apple has not implemented that option because it did not consider it necessary. Currently, the company is investigating the problem and has not officially ruled on the matter, but it is real, so do not play yourself silly with dates. The bug affects devices running iOS 8 or 9 on 64-bit processor, ie, all from the iPhone 5s, iPad and iPod. [Hoax Slayer via Guardian]
