Why are the dates mentioned all in 197?

197 is a change of computer era, and it is also the time initialization of computer network based on the epoch (January 1, 197 GMT), that is, the time initialization caused by a short episode BUG when the server or system was updated. This thing comes from the timestamp of Unix system, which is used by systems and programs to time. The Unix system stipulates that the timestamp of the current time is equal to the number of seconds between January 1, 197 and the current time, so when timestamp=, the time is January 1, 197. Then, the Android version of qq uses unix system, so it can't be seen by ios. Because the maximum interval between 32 bits to express time is 68 years, and the earliest UNIX operating system took January 1, 197 as the epoch time (start time) of UNIXTIME in consideration of the age of computer generation and the time limit of application, and java naturally followed this constraint? get? it? All the Android phones are wrong, but Apple's is fine.
