There are several date storage formats in the database, which need to be selected according to your needs:

1, timestamp: It can not only guarantee the performance, but also use its own time and date function.

2, int: suitable for time comparison, but poor readability.

3.datetime: Suitable for database data export, with high readability, but low query performance. (Not recommended)

4.varchar: Time zone is not supported. (Not recommended)
