The recent study of Python's regular expressions requires batch generation of random data. This involves to the module SYS, time in the Maxint, CTime, the code in the run CTime format times has been the error can not run.
After studying the relevant data, it is found that the Maxint value is different in the operating system, the MAXINT>2^32 is under the 64-bit operating system, and the number of seconds in the 32-bit operating system Maxint=2^32,ctime function is 0~2^32.
