What is the difference between UNIX TIMESTAMP and MySQL TIMESTAMP?

Both UNIX TIMESTAMP and MySQL TIMESTAMP are used to represent the date and time value. The main difference between these values is that UNIX TIMESTAMP represents the value by using 32-bits integers and MySQL TIMESTAMP represents the value in the human-readable format.

Example: FROM_UNIXTIME

mysql> SELECT FROM_UNIXTIME (1596222320) AS MySQLTIMESTAMP;

+---------------------+
| MySQLTIMESTAMP      |
+---------------------+
| 2020-08-01 00:35:20 |
+---------------------+
1 row in set (0.00 sec)

UNIX_TIMESTAMP

mysql> SELECT UNIX_TIMESTAMP ('2018-12-25 09:45:40') AS UNIXTIMESTAMP;
+---------------+
| UNIXTIMESTAMP |
+---------------+
|    1545711340 |
+---------------+
1 row in set (0.00 sec)
