What MySQL will return on adding microseconds in the timestamp value for converting it into an integer?

MySQLMySQLi Database

As we know that the value of timestamp can be converted to a number of seconds with the help of UNIX_TIMESTAMP() function. MySQL would ignore the microseconds added to the value of timestamp because the value of UNIX_TIMESTAMP is only 10digits long.

Example

mysql> SELECT UNIX_TIMESTAMP('2017-10-22 04:05:36')AS 'Total Number of Seconds';
+-------------------------+
| Total Number of Seconds |
+-------------------------+
| 1508625336              |
+-------------------------+
1 row in set (0.00 sec)

mysql> SELECT UNIX_TIMESTAMP('2017-10-22 04:05:36.200000')AS 'Total Number of Seconds';
+-------------------------+
| Total Number of Seconds |
+-------------------------+
| 1508625336              |
+-------------------------+
1 row in set (0.00 sec)

The queries above shows that the output remains same even after adding the 6 digits value of microseconds.
