（大意是将时间设为1970/01/01后重启，会导致64位版本高于IOS8的设备砖机）
Manually setting the date of your iPhone or iPad to 1 January 1970, or tricking your friends into doing it, will cause it to get permanently stuck while trying to boot back up if it’s switched off.
The bug within Apple’s date and time settings within iOS causes such an issue that users are reporting that the fail-safe restore techniques using iTunes are not able to repair the problem.
The date bug affects iPhones, iPads and iPod touches with 64-bit processors running iOS 8 or iOS 9, including the iPhone 5S or newer, the iPad Air, iPad mini 2 or the 2015 sixth generation iPod touch or newer.
The precise cause of the issue has not been confirmed, although speculation points to the way iOS stores date and time formats meaning that 1 January 1970 is stored as a value of zero or less than zero, causing every other process that requires the time stamp to fail.
