Changing the Date to 1970 on Your iPhone Will Cause a Major Glitch

Apple is working on a fix to a bug that prevents some devices from restarting.

Against their better judgment, some users have manually changed the date on their iOS devices, creating a glitch that prevents some devices from restarting, according to Apple's website. Users who have decided to travel back in time via their iPhones are currently advised to contact Apple Support in order to get them running again.

"An upcoming software update will prevent this issue from affecting iOS devices," a message posted Monday on Apple's website said.

While it's unclear what may be causing the glitch, it's worth noting the Dec. 31, 1969, date is significant in computer science because the following day, Jan. 1, 1970, GMT, is when the Unix operating system began tracking time.
