1970 bug

In the past few days, there was one hot topic on the social networks. At the very beginning, it might be one joke played by some users: if you set your iPhone time back to January, 1, 1970, your iPhone would be bricked. And then more and more people proved this and discussed it on SNS. Finally, Apple responded with the following words:

Manually changing the date to May 1970 or earlier can prevent your iOS device from turning on after a restart.

So how would that happen? Why is the iPhone 1970 problem and what can users do to fix the problem?

It is said that the 1970 iPhone bug is related to that iOS is Unix based system. And Unix time starts at Jan, 1, 1970, the time after the data is saved as seconds. And for users鈥 better understanding, the time is converted as needed. As for the time before Jan, 1, 1970? I guess Apple didn鈥檛 think their users would have the demand to go back 46 years ago.

So how to fix it in the end? Well, Apple said that they will fix the bug in the coming iOS system update. But I know the majority of affected iPhone users can not wait for so long. Here are two methods to solve this problem.


First, disassemble the bricked iPhone and take out the battery, then reinstall the battery after 10 minutes.

Second, lay aside your fully charged iPhone for several hours. When the numerical values of Unix based system is greater than or equal to zero, the system time will be effective and the iPhone can be restarted.

And finally, there is one kindly advice. Please don鈥檛 try this iPhone 1970 bug which seems funny. I know that some of my friends tried this due to curiosity and paid for that finally.
