According to relevant public information, it shows how python designs timestamp signatures as follows:

1 、>; & gt& gt import time

2、gt； & gt& gtt=time.time()

3、gt； & gt& gtprintt 1436428326.76

4、gt； & gt& gtprintint(t)/ 1436428326

5、gt； & gt& gt

6. Forced conversion means directly removing decimal places.
