Python gets the hours, minutes and seconds according to the timestamp.

? The timestamp can be simply understood as the number of seconds that have passed since1970/0101:00: 00. If you want to calculate the date operation, it is relatively simple and efficient to use the library that comes with the language. However, if only the time is taken in real time, it can be realized by modular operation and integer operation without relying on the library, and its performance is higher than that of the internal library function.

The calculation result is 6,543.8+0,000 times.

100000 times

The performance is nearly 200% faster. If there are millions or even tens of millions of calls involving big data analysis scenarios, the algorithm still makes sense.
