UNIX TIMESTAMPS 和 MySQL TIMESTAMPS 有什么区别?

In MySQL, UNIX timestamps are stored as 32-bit integers. MySQL TIMESTAMPS, on the other hand, are stored in a similar manner but in the human-readable YYYY-MM-DD HH:MM:SS format.

Example

mysql> Select UNIX_TIMESTAMP('2017-09-25 02:05:45') AS 'UNIXTIMESTAMP VALUE';
+---------------------+
| UNIXTIMESTAMP VALUE |
+---------------------+
| 1506285345          |
+---------------------+
1 row in set (0.00 sec)

The above query shows that UNIX TIMESTAMPS values ​​are stored as 32-bit integers with the same range as the MySQL INTEGER data type range.

mysql> Select FROM_UNIXTIME(1506283345) AS 'MySQLTIMESTAMP VALUE';
+----------------------+
| MySQLTIMESTAMP VALUE |
+----------------------+
| 2017-09-25 01:32:25  |
+----------------------+
1 row in set (0.00 sec)

The above query shows that MySQL TIMESTAMPS values ​​are also stored as 32-bit integers, but in a readable format with the same range as the MySQL TIMESTAMP data type range.
